Depending on what quantities you order, everyone should get into the habit of ordering from multiple different vendors for their supply. What I mean is, I "diversify" my purchases to spread out the risk, just like investing in stocks. Instead of buying 10 kits from one vendor, split between 2 or 3. Yes, you pay a little more with shipping and maybe the price difference. But, you have placed your own type of "insurance" on the product. "Don't keep all your eggs in one basket."
