Woah, some of those prices look crazy. $200 for a loose Magical Doropie?!? Loose copies have been selling for around $60 - $75, with CIB copies selling for $160 or so. MT Punch Out Gold for $200? Over the summer this title was consistently selling for the $120 range, loose, and I thought I overpaid when purchasing mine for around $150. To your credit though, the price of the most recent sales have been at around the $200 mark, though it seems odd of such a large increase in price, in a matter of months. Even many of your other prices look a bit "off" to me, compared to what they have been typically selling for.
You have some nice products, that is for sure, but I personally despise price gougers. Hell, maybe I would even purchase a few of your rarer carts (i.e. Tailor Made or Miss Peach) if you were offering fair prices.
Anyway, as a gentleman, I feel that if I am going to offer your some criticism, I will also offer you a reward in return. Free bump!
