Just to clarify, this is not really a group buy. You paid $406 + $65 (shipping) = $471 for the lot. Divide by 19 keyboards, and that's $24.80 per board SHIPPED. You are reselling them at $35 each PLUS shipping, PLUS an additional fee it looks like (and shipping could be less when paid on-line) making a good bit of profit in the process. This belongs in the Classifieds, and you need to have the boards on hand with photographs posted.
This thread will be moved to the Classifieds when you can provide that.
