Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
What product are you looking the best prices for?
Ok, I'm afraid I have no expertise in that area, I'll opt out and check with the other experts!
I HIGHLY recommend you do not post anything about this, ever thing on JA is searchable, I know what you are working with, this is very poor judgment dude.
I would venture over to reddit.com and find the right sub forum and ask there - that is your only safe answer.
they have vendor info there, that's all i can personally say.
