Some of those responses are clearly just friendly ways for others - often those who sell on TB themselves - to help bump your ad.
Others are more legit in terms of gripes - like being asked to drive to Buffalo or something.
As for your Paypal issues, that seems very odd to me. My inbound payments from buyers hit my account, and then if I choose to withdraw to my bank account (either TD or RBC), it usually takes about 3 days, and never more than 5. The % they take is a touch on the higher side, but when you factor in the time it takes to arrange a western union payment or something (which also have fees), it's usually worth it to not have to leave your computer and walk/bike/drive to who knows where.
