PayPal and Google Wallet offers the most affordable solution for anyone considering a commerce feature on their website. Because there is no start up or monthly fees (you pay a percentage of the online sale), it’s worthy of consideration.

Additionally, it is a relatively easy feature to incorporate into any website wanting secure transactions from a reputable vendor. Logically, a more sophisticated shopping cart comes with additional requirements such as a secure connection (SSL), merchant account and a monthly fees to maintain your online store.
