Many people have adopted from me and a critical question I always ask is, "do you have a food source ready for your Jumping spider's arrival"? A lot of time I am told, "No, I don't." So, with that in mind, I have you covered there as well. 
I had purchased from many Feeder businesses. Both big box stores and other places. No-one I had purchased from was any more than mediocre until I was tipped off to SPOODFOOD.COM (aka: The fruit fly store) - Not only was I impressed by the way that my cultures arrived, but the production and price was great! I also purchased mini mealies, and they are the best! Now, they carry blue bottle fly spikes!  (Flies are a Jumpers favorite) - How can you go wrong when you can get all that you need from one place? The cost is competitive, and the quality is outstanding?! All you need in a one stop shop! Many other Hobbyists and Breeders recommend this small business! I do too!
