If there are days when you need something quick, savoury and affordable without spending too much, this latest collaboration between Old Chang Kee Singapore and 7-Eleven Singapore is worth knowing about. The popular Curry’O & Egg Mayo Double Combo Sandwich is back, giving sandwich fans another chance to enjoy two very different flavours in one convenient pack for just $4.

The promotion is available now until 3 November 2026, although shoppers should take note that it is only available while stocks last. That makes this a particularly useful deal to remember the next time you are stopping by a participating 7-Eleven outlet and looking for a quick bite.

Old Chang Kee is well known in Singapore for its savoury snacks, particularly its curry puffs and other convenient treats. This time, however, the spotlight is on a sandwich combination that brings together the familiar savoury character of Curry’O with the smooth and creamy taste of Egg Mayo.

The idea behind the Double Combo Sandwich is simple. Instead of having to choose between two flavours, customers get both in the same pack. For people who enjoy variety, that can make a quick snack feel a little more satisfying.

Two flavours in one $4 pack

The main attraction of this promotion is, of course, the price. At $4 per pack, the Curry’O & Egg Mayo Double Combo Sandwich is an affordable option for a quick meal or snack while out and about.

The Curry’O side brings a savoury curry-inspired flavour, while the Egg Mayo provides a creamier contrast. Having both together means the pack does not feel quite as repetitive as buying a single-flavour sandwich.

It can work particularly well when you are hungry but do not want a large meal. Perhaps you are heading to work, taking a break during a busy shopping trip, or simply looking for something easy to eat on the way home. A ready-to-eat sandwich can be a convenient choice, and the $4 price makes it easier to fit into a small food budget.

For fans who have tried the sandwich before, this promotion also gives them a reason to pick it up again. The fact that the Double Combo Sandwich is described as being back by popular demand suggests that there is already an audience familiar with the combination.

Why is this deal worth checking out?

One of the biggest advantages of this promotion is its straightforward value. There are no complicated spending requirements mentioned in the offer. Customers simply look out for the Curry’O & Egg Mayo Double Combo Sandwich at 7-Eleven and pay $4 per pack, subject to availability.

That makes it an easy deal to consider when you are already visiting a 7-Eleven outlet.

The combination of flavours is another reason to give it a try. Curry and egg mayo offer noticeably different tastes, so customers who prefer a little variety in their food may enjoy having both options together.

It is also a practical choice for people who do not always have time for a sit-down meal. Singapore’s busy lifestyle means convenient food can be useful, especially during a packed working day. A sandwich can be taken along for a quick lunch, afternoon snack or light evening bite.

And because the promotion runs until 3 November 2026, there is still some time to look out for it. However, the important phrase to remember is “while stocks last”. The end date does not necessarily mean every outlet will continue carrying the sandwich until that day.

A convenient stop at 7-Eleven

The collaboration with 7-Eleven makes this offer particularly convenient. 7-Eleven outlets are located across Singapore, making the retailer a familiar stop for drinks, snacks, groceries and quick meals.

If you are already passing a 7-Eleven, it is worth checking the chilled or ready-to-eat food section to see whether the Curry’O & Egg Mayo Double Combo Sandwich is available.

This is also the sort of promotion that can be useful for spontaneous purchases. You do not necessarily need to make a special trip just for a sandwich. If you happen to be nearby and spot the promotion, $4 is a relatively easy price point for trying something different.

For office workers, students and commuters, the sandwich could also be handy when hunger strikes between meals. Rather than spending considerably more on a full restaurant meal, a $4 option can help keep the cost of a quick bite under control.

Good for Curry’O fans and sandwich lovers

Those who already enjoy Old Chang Kee’s savoury flavours may find this promotion especially tempting. Curry is one of the brand’s familiar flavour profiles, and having that taste incorporated into a sandwich creates something slightly different from the usual curry puff or snack.

Meanwhile, the Egg Mayo component provides a more familiar sandwich filling that can balance the stronger savoury curry flavour.

The Double Combo format is probably the most interesting part of the offer. It gives customers two flavours without needing to purchase two separate products. If you are sharing a snack with someone who prefers a different flavour from you, it can also be a convenient option.

Of course, availability may vary from outlet to outlet, so it is sensible to check before making a special journey.

A small treat that does not cost too much

Not every good food deal needs to involve a huge discount or a complicated promotion. Sometimes, getting something enjoyable at a reasonable price is enough.

At $4, the Curry’O & Egg Mayo Double Combo Sandwich falls into that category. It is a simple food promotion that can suit customers who want something convenient without committing to a more expensive meal.

It can also be a nice little pick-me-up during the day. If you are taking a break from work or running errands, grabbing a sandwich and a drink from 7-Eleven can turn an ordinary stop into a quick snack break.

For regular 7-Eleven shoppers, this is even easier to consider because the sandwich can simply be added to an existing shopping trip.

Remember the deadline

The promotion is available now until 3 November 2026, subject to stocks lasting. Since ready-to-eat food promotions can sell out earlier than expected, anyone keen to try the Curry’O & Egg Mayo Double Combo Sandwich should not necessarily wait until the final day.

The best approach is to check a nearby 7-Eleven whenever you are in the area and see whether the $4 pack is still available.

Ultimately, the appeal of this promotion is its simplicity: two sandwich flavours, one convenient pack and a $4 price tag. For anyone who likes Old Chang Kee, enjoys trying limited-time food items, or simply wants an affordable snack while out in Singapore, it is a deal worth keeping an eye out for.

So, if you are heading past a 7-Eleven over the coming weeks, take a moment to check the shelves. The Curry’O & Egg Mayo Double Combo Sandwich may be just the convenient and budget-friendly bite you are looking for.
