We have now a new thread where member can express their wishes for new cards for the Ishop ( thanks Aaarin!). As I read the suggestions, I couldn't help but notice that some of the characters mentionned already had a card in the shop. That's what made me think if maybe it would be time to retire some of the old cards that are actually in the shop. I don't know if there is a method to determine if a card "has run it's course" before adding new ones.
Some cards were highly popular and were purchased by a LOT of members. I noticed that some of them haven't seen their numbers go down quicky after the last time the cards were re-stocked. I don't know...maybe most of the members who had an interest already made their purchase (lv1 Luffy, anyone???)
There are also other cards that were never popular to begin with. For example, all the cards Meine Liebe Wieder never found more than 10 buyers to purchase them.
The only problem I foresee with retiring a card would be that I don't know if the members who have them wouldn't be able to sell them back. Unless they would get get points for the selling without having the card re-stocked.But then again, I still believe if would be better than having an endless number of cards available.
