Friend eventually moved and found a different warehouse club that was more convenient to their new place so we had to get our own membership na. So far, it (the fee we paid) doesn't seem too bad. But then again, last year, I had that part time thing.
* Sis and I had a good method, I'd check out the costco coupons as soon as they get posted online on blogs and if there are items that I'm interested in, Achi clips coupons from her coupon book and sends me some. Fortunately, all the coupons for all products have the same code so it doesn't really matter if you hand in the actual coupon for the product or for something else (in case there are items that we both want).
