where can I find good cheap bulk bubble mailers. please guide me in the direction!

You can get them by the hundreds on ebay for relatively cheap.

Kraft #0's are pretty good. Here's an eBay link for some: http://www.ebay.com/itm/250-0-6x10-Valuemailers-Brand-Kraft-Bubble-Mailers-Padded-Envelopes-Bags-/300921212222?pt=BI_Mailers_Envelopes&hash=item46104d4d3e.

I can usually get 2 for a $1 at a dollar store

Walmart, 10 packs are 4.50

I can usually get a pack of 25 of these (http://www.gianteagle.com/43100760863.aspx) at my local grocery store for $2.00. They dont have the bubble packaging in them but in all the trades ive used them in (150+) I have never had that be an issue. I usually just put the cards in between 2 toploaders per the usual and stick them in a plastic baggie and practically serves the same purpose of waterproofing and cushioning the cards in transit. Plus its perfect size that fits the Paypal shipping label just by folding it in half. To each his own I guess but its def saved me plenty of cash on shipping supplies. AND I dont have to pay SHIPPING costs to to have SHIPPING supplies sent to me. Which reminds me I need to get some more lol...
