Ok im new here (only been browsing since yesterday :P) so plz dont flame if ths has been posted b4 or sumfing. Im not sure if this can be considered and scam but it works and can help u sell items for much more than normal on AH.
What u do is whenever u get a nice item (blue or epic pref, to be worth the effort) put it on AH for a rip off price. Then log an alt and say WTB w/e item u have on AH, and say u wanna buy it for like 10-20g or something more than ur BO price on AH. Any1 browsing the AH who sees it will want to exploit this opportunity and BO ur item, and whilst they are on their way to sell to ur alt just DC or sumfing. Near guaranteed sell and u can get a few g on top of what it would usually sell for.
And to any1 who willsay ppl will think "why doesnt he just search AH", most ppl will just want to exploit this n00b, kkthxbye.
