Apparantly all4btc.com is not trustworthy anymore and doesn't do its work. (If you are affected you really should sue them by the way. Their names are available publically. Their company is called "bitsandcoins Consulting UG")
Is there any alternative for this? Purse.io seems to only do it for amazon stuff. But I'm looking for one that actually offers it for any internet order on any site like all4btc did.
