for the spectral toger scam it's good to ask them if they have an msn and send them a pic of a card. This will get them more interested and also you don't need to get HUGE offers u just need a lot of small offers those will build up and bring in a ton of profit. also unless it is a big offer don't take half. (when i say big like 1k+)
Here's a pretty good pic of the card for spec tiger
