Items purchased may be returned for free if they are not as described. The buyer pays shipping for any other return. Merchandise must be returned in the same condition in which it was sent.
The buyer pays the actual shipping cost based on the weight and size of the package. I never pad the shipping cost for extra profit.
Media Mail and 1st Class Mail are used whenever possible to lower the shipping cost.
I pack carefully with bubble wrap and double boxes as needed for fragile items, and I use packing paper and packing peanuts as filler.
I'm happy to combine shipping assuming individual items can go in the same box without risking damage.
