When setting your shipping preferences and prices please note:
Shipping options on your product page will list in the order of least expensive option first. Because "pick-up" option is free, it lists on the top of all shipping options. So, if your buyer does not realize they have not selected a shipping method, it would default to "pick-up". For that reason, some sellers only state that pick-up is an option inside their storefront or product description only, They do not as a shipping choice to prevent having to either go back and ask the customer later (hassle) or have to pay the shipping themselves (lame!).
