Just another suggestion, but if RW/GF are not willing to add requested items then why not put current items on sale on a rotating basis? I don't just mean the four or five items but all of them. For example, for each category (upgrading, commodity, costume, etc.) there would be 2 items placed on sale each weekend. The following weekend it would be 2 different items per category, and you keep going until every item has been on sale at least once and then restart the process. FYI, sales should be more than 1 or 2 dias less than the normal price.
