There is no "best place" or "best company". My limited experience so far first order from Peak SeedsBC Canada stolen, it was resent, stolen again, then I changed delivery address, "stealth" order from same vendor came through, then stealth order from Sannies (NL) came through.
There are always risks and losses in seed buying business. Make sure you buy from reputable seed company, do your homework and go with the most reputable vendors, there is a few out there, out of a hundreds.
