Little Cow Shop review for ShoppingGives ‑ Donation App

I had this app for a little bit before they started charging and don't get me wrong I think it's a great app but the reason I'm giving it 2 stars is that I HATE that they started charging out of nowhere. I'm still figuring out how to get sales in my store and I'm not gonna pay 29$ a month when I'm getting 1 sale a month. It makes no sense. What would make more sense is if they required me to pay after a bigger amount of sales or after making a certain amount of profit. Once I have a lot of sales I wouldn't mind paying at all. It's a great app but only worth it once you get sales and if I still had the donation part of it, I might get more sales. But I can't afford it until I get sales. See how difficult it is for us small business owners? So I'm gonna have to go with a different app, which stinks.
