Need help with monthly charges

So apparently every month i get charged by Meh.com a total of $5. I was willing to be okay with it because i thought it was due to the membership plan for shipping, but it wasn't. I JUST bought the fuku for April 21st and clicked the membership shipping and it still charged me $5 extra. So far it has charged me for 2 months not including this month. Can someone tell me what i was being charged for? Because i know i didn't click on some random reoccurring purchase.
