I've been searching for samples and found that it can be a pita to find shops that sell per chip and don't charge out the rear for shipping. This article will give you a consolidated list of the best places I've found to order samples from.
To avoid having to pay shipping costs multiple times I tried to find shops that stock a wide varitey of chips.
I'm not including chip costs since a difference of .20-30 on a dozen chips isn't that much of a difference. Shipping totals are for 20 chips unless otherwise indicated.
Clicking on the chip pictures will take you directly to that vendor's website. Hold your mouse over any picture for more information about that chip.
Check venders site for pricing and shipping. This vender offers the sale of individual chips (1 chip at a time) so you can build a sample set of the chips you are interested in. They also offer full sample sets of each type of chip (full set of Mardi Gras clay with denominations - 9 chips). Apache Poker Chips - Chiptalk.net Sponsor!

Las Vegas Clay (ebay)
Las Vegas "Clay" (They aren't really clay. They are, however, the chips I ended up buying, so I'm adding them)
This ebay store sells a sample set of 7 for .99 with shipping of a couple dollars. I ended up buying from Okumart, which had a better price on chips at the time. Both sellers were fine to deal with and had fast shipping
