I fully agree with you Admin.
In fact, the reason I suggested Costco is that the return policy for returns & exchange is 30 days with out any questions ask! I've experience it in the past when buying a TDK CDR-RW thinking it would read cdg's but it didn't!!
Buying a Plextor from MTU is by far the best option for US customers but it turns out to be quite expensive for Canadians due to exchange, shipping & custom clearance, expect to pay at least $200.00 CDN. At that price you get the Plextor DVD-RW
