Bad advice...unless you just like losing money. BBCE's buy price on a wax case is $1300 ($65/box). You can do much better than that on eBay selling them yourself. Wax boxes seem to be going for $90-$100 on eBay.

Take good pictures of the unopened case to let the buyers know your boxes came from a sealed case and they will bring more money.
