The thing that makes me uneasy about many international sites is the expectation of the buyer to buy bulk from the start. On a dw market for instance, I would never buy bulk without first receiving free sample or at the very least buying small quantity or just paying for shipping. So at the very least I know the vendor is competent in shipping & thar the product is acceptable. For the substance I'm interested in, to start I only need 5-10grams. Obviously, the amount will go up with time. But when I put feelers out, sellers were trying to get me to buy kg or 5kg quantity. The way I look at it, its better for both of us to see if 5-10grams makes it to destination, amount of time for shipping, tips I could give to seller for future ships that they may not know (don't handwrite addresses, vacuum seal or use airtight Containers followed by mylar etc.). These are things I would like to make certain during small quantity ships that either side could afford to lose n alter shipping on next load rather than just shipping kg n I'm out the Crypto, the seller is out of future purchases unless they do reship etc. . I think this is why ppl love the escrow of dw markets so much.
