i can understand where some of the sponsors come from tho - ive had a few experiances my self in that department in private sales.
"hey man im interested in XXX, postage too XXXX"
yeah sure man, give me your full name and address and ill send you my bank details
"my name... my address"
hey... thats for that here's my details, let me know when you've put your money thru
"will do"
2 weeks later nothing and yet another person has my bank details pointlessly.
i completly understand where they would be comming from... and if your busy on top of that, its not like you want to deal with the potential of lost sales because some joker cant let you know that there not getting it.
