I also appreciate your opinion, and wish I did have "shades of gray" in my thinking.
I am, as you probably have noticed, very "north/south".
I think many people purchased the mug before the rule change in 2000/2001 without knowing what the policy was and from what they read on a BB somewhere. I know many people purchased them after the rule change and have said, I did not see any rule, where are they posted, etc. etc. Or, my friend bought them years ago and they said you can use them for life.
Since they do not seem to change the design it is impossible to tell, so, many are ignoring the rule. Most especially the ones that purchased mugs at resorts that opened AFTER the rule change.
Obviously, the only place this is a hot spot is on BBs. Disney certainly does not seem to care, but, I do believe they are watching and there will be a cessation of the plan or some modification of the plan.
Verbal contracts do not stand up in court, most especially from folks who are not in a position to set policies. I bet IF this were to be tested in court, you would find Disney would win.
I pay very little attention to what is being sold on ebay. It used to be a great idea until people found a way around the system and have decided to sell stuff for a small amount and gouge you on shipping because they don't have to pay a fee on shipping. Ultimately, that will cost the folks that have been honest since the beginning of ebay. When I do purchase items (mostly drink coupons for SWA) I only purchase from the folks that charge a decent price and a reasonable shipping fee. IE: 2 books of 12 coupons = 6.00 and 1.00 shipping.
