for those who do groceries I thought I just chip in a few stuff here and there. Amongst all the supermarts seems like tescos offer more dollar for dollar. if you do pay in SGD the exchange is very good currently they're doing 1=2.46 to 2.47 you pay sing they return you rm.
Jusco's the equivalent of cold storage sort of vaguely. They have a good collection but are the most expensive. Fruits and vegs tend to be much better than tescos in terms of quality. Tescos is a bit of hit and go. sometimes good mostly just ok and can be very bad esp. for fruits. Giant/carrefour/mydin are the inbetween of the 2 mostly. Tescos are not created equal either. Tescos bukit indah is freaking cold and this coming from someone who can generally withstand or like cooler temperatures... Seems like Tescos plentong is the cheapest amongst the whole chain in JB. I always manage to find very good deals from there e.g. nestle biomega enriched UHT milk retails for there abouts rm5.5 but can go for rm3.50 even cheaper then the usually cheapest, marigold (rm 4.45 thereabouts) when i see those i swipe at least 10 saving me rm20 just on milk alone (uht milk can keep longer). they also do more reduced/discard priced items (yellow price labels) than other branches. Though you've really got to hunt for the intact/good stuff. The cheeses omg, i swear all the leftover cheese are sent to plentong. I have bought ricotta for rm 5, mascarpone for rm3, cheddar for rm4-5, feta/goat cheese for rm7-9. the last one usually original priced at ~rm40. Italian chianti is almost always on sale and its of good quality.
Those looking for fresh meats. Kipmarts have more to offer comparatively.
Finally, don't be fooled by 'promo price'. I like to get individually oat biscuits weekly and i ever see items on full price but with a promo tag??! must shop enough to remember the approximate price to know when is it a deal or not. Also, good deals usually begins fri through to sun (sat is BYOB across the board or pay for plastic bags). don't buy the engine oils there. First they have insanely thick oils mostly e.g. 5/10/15W50 and they are exp compared to SG even after factoring conversion for 'discounted' oils. Giant in sg have very good engine oil deals once in a while. esp. mobile 1 fully synthetic series. those really cheap ones you see in JB are mostly mineral oils or semi synthetic so be careful when you buy. Giant in JB seems to have one of the best collection (compared to others) for car barang barang like the shampoos, dashboard cleaner etc.
that's it for now i think?
