Everything is 'free' or rather $0.00 until you get to the payment stage, when "Shopping Cart Items do not meet the Minimum Purchase Price of $3.50" message is displayed. Minimum pricing for card and other electronic payments is now illegal in some places, including the EU. You can refuse to sell me something of low value if I want to pay on a card but you can not insist that I pay a minimum amount for using that card. You can have a store-wide policy of a minimum sale value. It is not clear on what basis the minimum price is charged, though I'm sure your lawyers would say it's the store-wide policy, in which case you should make that explicitly clear.

In that case you can not offer an item for $0.00 without breaking the policy. You should not be asking for CC details for a zero value transaction, this looks like data harvesting.

Surely the point of offering this figure for free is to let people assess it: if they like it they'll buy stuff for it, why are you messing this up?
