Pay Per Acquisition differs slightly in that the user is offered a free sample, in most cases of a physical product, they simply have to pay for the postage and packaging. These offers pay out large amounts as it requires your visitor to have a credit card and be convinced enough to place the order even though the offer is 'free'. You may notice that the shipping and handling fees are slightly (or in some cases, blatantly) inflated from what you would expect to pay, and just like eBay, the companies here are making the money on the S+H fee. Pay Per Acquisition pays out very high amounts, ranging from $5 to $50 per completed offer. This is mainly because by ordering a free sample, the visitor becomes a very hot lead to the company in question; they have demonstrated a high level of interest and they have shown that they have the means to buy more of their product if required.
