Simple enough: cancel your membership if you are not happy. The membership fee is prorated, and you will receive a refund for unused days. There are so many complaints about items going up in price. What about the prices that have been going down? It's your money; spend it where you are happy, but stop complaining. I'll continue to shop at Costco, the complainers won't be missed.
Yeah - to me this is like people buying airplane tickets. So many people buy the cheapest ticket offered, which simply means that they have purchased a seat on a flight. Then they complain when the airline exacts a charge for services that are baked into the higher priced fares they shunned.
I think that if it is important for flyers to have seats where the travelers are all seated together, or where they will have an aisle seat, or to use overhead bin space, then the flyers should be ready to pay for that privilege. Instead you often see complaints from people who, having bought the cheapest ticket possible (which means that they will be placed in whatever seats are left over after people who did purchase seat selection have made their choices), are now complaining because they haven't received seats that meet their needs. People want to have their cake and eat it too.
To me this is a bit like timeshare exchangers, who complain that, as exchangers they were assigned to the dregs of the inventory remaining after owners made their reservations, and their reservation requests were not honored by the resort. To my thinking, the first obligation of the resort is to accommodate owners who are making reservations. Exchangers should get what is left over after returning owners have made their selections.
