No app is cheapest for everything, and any guide that claims otherwise is selling you a shortcut that does not exist. The smarter question is which app tends to win for each kind of item, and why. Prices move constantly, so treat what follows as a way to think about your basket rather than a fixed rule to memorise. The goal is to know where to look first, then confirm with a quick live check.
Fruits and vegetables
Fresh produce prices swing the most between apps and through the day, because stock and quality change fast and each app sources differently. This is the category where comparing every single time pays off the most. It is also where the gap between the cheapest and priciest app on the same items can be widest, so a ten second check before you add to cart is genuinely worth it. Do not assume last week's winner is this week's.
Monthly staples
Rice, atta, oil and pulses are bought in volume, so even a small price gap per kilo adds up to a real number across a month. Larger packs and the right app on order day make the biggest difference here. Because these are planned purchases rather than impulse ones, you usually have the time to compare properly and to buy in bulk when the price is right. This is the category where a bit of patience is rewarded the most.
Snacks and packaged goods
Branded packaged items tend to sit close to MRP across apps, so the base price is often similar wherever you look. That means the winner in this category is usually decided by coupons, bundle offers and delivery deals rather than the shelf price itself. Read the total after offers, not the sticker, and watch for multipack pricing that quietly beats buying singles.
Dairy and daily needs
Milk, bread, eggs and other daily items are small-ticket but frequent, and the frequency is the whole point. A few rupees of difference, repeated every couple of days, quietly compounds across a month into something you would notice as a lump sum. Picking the consistently cheaper app for your regulars is a small, boring decision that keeps paying you back.
Household and personal care
Detergent, cleaning supplies and toiletries are bulky, occasional buys where per-unit price and pack size matter a lot. Because the packs are large and you buy them rarely, the saving on a single smart switch can be meaningful. These are worth comparing carefully rather than grabbing on autopilot, since the difference between apps on a big pack is rarely trivial.
How to actually use this
The cheapest app for each category changes, so the reliable move is not to memorise a winner but to use these tendencies as a starting point and confirm with a live comparison before you buy. Comparoo does exactly that across all of them at once, and can split a mixed basket so each item comes from wherever it is cheapest on the day you order.
