I love looking for deals on shop goodwill, but be prepared to add about $10.00 to the final cost of your item due to handling and shipping charges. Handling is usually $2 to $3 and shipping seems to always be around $7 give or take a dollar or two.
I buy from eBay all the time and never pay this amount for shipping and handling. I am shopping less and less on goodwill, because I don't want to pay $10 to deliver a $3 pair of earrings. Double check shipping charges before you buy from goodwill.
