If you are someone who enjoys picking up an iced coffee or matcha drink during the workday, there is a little September treat worth knowing about at Hi Coffee at Guoco Tower. For a limited time, customers ordering selected iced Japanese lattes can receive a couple of useful extras without paying more for them.

From 15 to 30 September 2026, Hi Coffee is running a September promotion that gives customers a free reusable thermal bag together with a free upgrade to oat milk when ordering an eligible iced Japanese latte.

It is the sort of promotion that may sound simple at first, but it is actually quite practical. Instead of carrying a cold drink around in your hand and worrying about condensation or keeping it cool, the reusable thermal bag gives customers something they can use again for future drinks and other occasions.

And for those who prefer oat milk, the free milk upgrade makes the deal even more interesting.

A Free Thermal Bag for Your Iced Drink

One of the main highlights of this September promotion is the free Hi Coffee reusable thermal bag.

Anyone who regularly buys iced drinks will know that carrying a cold cup around Singapore can sometimes be a little inconvenient. There is always the condensation on the outside of the cup, and if you are walking around or travelling home after work, having a proper bag to carry the drink can certainly make things easier.

The thermal bag is also not designed to be a one-time-use item. Customers can keep it and use it again, making it a practical little extra rather than something that simply gets thrown away after the drink is finished.

It could come in handy for another takeaway drink, a small food purchase or even when heading out for a quick errand. For a promotion that is centred around a drink purchase, getting something reusable to take home gives the offer a little more value.

Do note that the thermal bag is available upon request, so customers should remember to indicate that they would like the promotional item when ordering.

Free Oat Milk Upgrade Included

The second part of the promotion is particularly appealing to anyone who already enjoys oat milk with their coffee or matcha.

During the promotion period, customers can enjoy a free upgrade to oat milk with the eligible drink. Normally, an alternative milk option can come with an additional charge, so having the upgrade included gives customers another reason to consider trying the promotion.

Oat milk has become a popular choice for people looking for a different texture and flavour in their drinks. Combined with an iced Japanese latte, it can make for a refreshing option when Singapore’s weather is warm.

If oat milk is already your usual choice, this is an easy way to enjoy it without having to pay the usual upgrade cost. If you have never tried it before, the promotion also gives you an opportunity to see whether you prefer it over the standard milk option.

What Drink Is Eligible?

There is an important condition to take note of before heading down.

The promotion is available for Iced Japanese Lattes only. This means customers should not assume that the free thermal bag and oat milk upgrade apply to every drink on the Hi Coffee menu.

If you have a particular drink in mind, it is worth checking with the staff when placing your order to make sure it qualifies for the September promotion.

The thermal bag is also subject to availability, so it is best not to leave your visit until the very last day if receiving the reusable bag is an important part of the deal for you.

Why Should You Go and Enjoy This Deal?

There are several reasons why this promotion could be worth adding to your coffee or matcha stop this September.

First, the offer combines two different extras in one promotion. Customers get a free oat milk upgrade as well as a reusable thermal bag when ordering the eligible iced Japanese latte.

Secondly, the thermal bag is something that can continue to be useful after the promotion has ended. Rather than receiving an item that has very little practical purpose, customers can keep the bag and use it again for future takeaway drinks.

Thirdly, Guoco Tower is a convenient location for people working or spending time around the Tanjong Pagar area. If you are already nearby for work, shopping, appointments or other errands, stopping by Hi Coffee can be an easy addition to your day rather than requiring a special trip across Singapore.

The promotion may also be worth considering if you enjoy trying small seasonal offers. You get to enjoy your usual iced drink while receiving an extra milk option and a reusable accessory at no additional promotional cost.

For regular coffee and matcha drinkers, these little extras can make a takeaway purchase feel more worthwhile.

A Handy September Treat at Guoco Tower

The location itself makes this promotion particularly convenient for office workers and anyone spending time around Guoco Tower. Located at B2-K1, Guoco Tower, Hi Coffee is situated within a busy area where a quick drink stop can easily fit into a lunch break or afternoon routine.

Imagine finishing a busy morning at work and deciding that an iced Japanese latte would make the afternoon a little better. Instead of simply picking up the drink, this promotion means you can potentially walk away with a reusable thermal bag as well as your chosen oat milk upgrade.

That makes it a nice little treat without needing to spend extra simply to enjoy something different.

Of course, customers should remember that the promotion is only available for a limited period. The stated promotion period runs from 15 September until 30 September 2026, while the reusable thermal bags are available while stocks last.

So, if the free thermal bag is what catches your attention, visiting earlier during the promotion period may be sensible rather than waiting until the final few days.

A Simple Deal for Coffee and Matcha Fans

Not every promotion needs to be complicated to be useful. Sometimes, the most attractive offers are the ones that add something practical to a purchase you were already planning to make.

Hi Coffee’s September promotion falls into that category. Order an eligible iced Japanese latte, request the promotion, and customers can enjoy the free oat milk upgrade together with a reusable thermal bag, subject to the stated conditions and availability.

It is particularly suitable for people who enjoy iced drinks, like oat milk, or simply appreciate reusable takeaway accessories that can be used again.

If you are around Guoco Tower before the end of September, this could be a good opportunity to make your next iced Japanese latte a little more rewarding. Just remember to request the thermal bag when ordering and keep in mind that the promotional item is available while stocks last.

For anyone looking for a small September coffee treat in Singapore, Hi Coffee’s limited-time promotion at Guoco Tower is certainly one to keep on the radar.
