奇怪
为何台湾好市多不能退差价 我在美国 加拿大都可以price difference.
只要到柜台跟他们说某某东西本周有特价 我之前买的同样商品 他们都退我
5-10元 好像是要在销费的一个月内
Costco has an unwritten price adjustment policy that members can take
advantage of to get a refund for the difference in price if an item they buy
is marked down within two weeks or so, Wang said. So hang onto your receipts,
especially if you buy seasonal items before they are marked down
