I'm thinking of using PayPal for a product launch, but a few questions are troubling me. If you go from taking small amounts of cash to all of a sudden taking $5k in 24 hours will PayPal lock down the funds and put you under investigation? The other question is I only wanted to sell a small limited quality to begin with, does paypal let you limit the quality you want to sell? The last question would be which payment processors, welcome product launches and offer all the tools an internet marketer needs to control the process? Thanks.
