Vintage Treasures At low Prices I'm a small shop and depend on ebay to pay bills. I'm human make mistakes and not perfect please give me the opportunity to make things right if not completely satisfied.*Ebay has something called (DSR's) ‘Detailed Seller Ratings.’ It is the star system at the bottom of the feedback page. PLEASE LEAVE 5 STARS! It is very important . If there is a problem with item please contact me before opening case or leaving dsr ratings! The way ebay has it worded, 4 stars sounds pretty darn close to perfect, but as a seller, if I don't average higher than 4.9 stars, I could lose selling privileges. Please take this into account when leaving the Shipping Handling, Item As Described, Shipping time stars and leave a 5 across the board :-) **I FOLLOW ALL EBAY POLICES AND STRIVE FOR 5-STAR SERVICE EACH AND EVERY TRANSACTION. WHEN YOU GIVE 4 STARS IT MAY SEEM LIKE A GREAT SCORE BUT, A 4 ON ANY STAR IS 4.0 AND EBAY CONSIDERS THIS A SUB-PAR MARK SINCE THE REQUIREMENT IS 4.9. IF YOU ARE PLEASED WITH THE TRANSACTION PLEASE RESPOND WITH ALL 5 STARS. IF YOU ARE NOT PLEASED LET ME KNOW AND I WILL WORK TO MAKE IT THAT WAY. Feedback: Due to recent ebay policies regarding feedback I'm dedicated to my buyers in providing a 5 star customer service rating-but I do have a life outside of this wonderful world of ebay and sometimes make mistakes- I'm human too. Please be kind to sellers and consider that they to have lives when using the new rating system. Practice patience & understanding & please give a 5-star rating on each DSR or contact me if you are not satisfied.
