I mailed them stating how a good escrow is unavailable and wanted to buy a DELL inspiron using BTC as payment. They said they are willing to accept my offer. I just need to raise few more to get one

What?
YOu really mean it ?
They will accept Bitcoin for payment ?
How ? can u show us a SS of the convo you had with them ?
Here ya go. I just used my phone call to talk to Amazon.in people and so can't show a screenshot really. Hope it helps
