Source for 12" LP Mailers, or Pizza Boxes?

[byto253]

I will be listing a 100 or so 12" LPs and am looking around for shipping boxes to order.  It looks like it is a better deal to order pizza boxes vs. LP mailers.  Not to concerned that they are bigger than needed for 1 or 2 LPs as long as it is ok for US tracked packet.

Any of the LP sellers here have any suggestions?

Good tip about Rakuten.   I have not used them since they ebates but that is worth looking into.

Ended up going with mailers from duplication.com at $99 for 50 including shipping.   It is a big box, so glad I just went for 50 for now.   The decider was the postive reviews and one that indicated they were able to easily stay under 500 grams.    I didn't find any site that gave the actual weight of the mailers.   These are 150 grams, so with the LPs weighing in around 220 grams they will be under 500 grams, even with some additional backing.
