Hi !
I'm also looking for something able to cart an article defined by i think two parameters that are in its name (keyword, number, etc...), checkout with paypal and complete transaction in an Etsy shop.
Something that can act faster than any human being and faster than other bots used against the same shop , maybe with multi threading to maximize simultaneous attempts.
If you can help, please send me directly a PM (as I can't because I've post less than 15 messages).
