I am brand new to keeping mantids for pets, and I ordered twice from Carey at Green Oasis (
http://mantispets.weebly.com/). Carey was extremely helpful in setting me up and giving me advice, I thought her prices were reasonable and low, and she was very prompt at both replying to emails and shipping. She took care to package the mantids properly with padding, insulation, and food/water for the shipping time, and they arrived safely.
Overall, I was very pleased with my transaction with GreenOasis, and I'll definitely look forward to doing business with her again in the future.
