Straight from the PuckerButt Pepper Company! They're the ones who bred the Reaper and offer seeds, mashes, and sauces alike.

Baker Creek Seed Co (rareseeds.com) is my favorite place to order seeds from. Nice family run business with an absolutely massive selection of seeds. Free shipping.

Their free color catalog just came out last week: https://www.rareseeds.com/requestcat/catalog/

I bought various chili types seeds in the past from them without any problems.
