I just got back from alderwood and premium outlet @_@
usually nothing much to buy at the outlet la........only bought a pair of converse and sunglasses after 2 visits..........lol
If you use Cad $ credit card, say today exchange rate, ~ 1.01, they may charge you $1.03-1.04 as exchange rate .. however, if you use a US$ credit card, you can buy US$ yourself, and pay the bill.
Way more variety of products. Of course...the product that I used....only available in US costco but not the Canadian one...
e.g. dental floss...Canadian Costco sells the Oral B one that I don't really like....US Costco sell the Crest "Glide" which I found really good!
US Costco has Carnation Evaporated Milk (a.k.a. 三花淡奶) but not in Canadian Costco.
