I have recently came into information that is common sense, but probably not thought of until it is already to late. Some listings show sizes and measurements and some do not, but always ask for measurements if you are not sure about the exact size...it will save time and money. If an item is listed as used; ask for additional pictures; this will help in determining what the item will look like when it arrives. If something is listed as used (even once)...it may need to be washed before shipping.  Do Not be afraid to ask the seller to launder the item...after all if they want to sell it, it should not be a big deal. Good Communication between the seller and the buyer is very important. It can save feelings from getting hurt and time.  We do not know who we are communicating with beyond the screen, but they could be a returning customer..so always use good communication.
