Are you looking to promote BYOTs or build them?
If you want to promote BYOTs, I've got
http://www.byotbucks.com for ARS and I have some with Epic Cash that are getting great conversions but I haven't been able to find time to finish the site for them yet. If you'd like to know about them, ICQ me at 4600137 or e-mail eightiegirl -at- comcast dot net.
