SHIPPING CHARGES ARE CHANGING. SLOWLY ALMOST ALL LISTINGS WILL BE CONVERTING OVER TO SHIPPING THAT IS CHARGED TO BUYER. LAST YEAR SHIPPING CHARGES AND SHIPPING SUPPLIES REALLY TOOK A NUMBER ON MY BUSINESS. SO TO KEEP AFLOAT CHANGES HAD TO BE MADE AND THEY WILL BE CHANGING OVER SLOWLY POST BY POST. BUT ALSO PRICES ON ITEMS WILL BE GOING DOWN A LITTLE TO HELP WITH MAKING SURE MY CUSTOMER STILL GET GOOD DEALS. WITH THIS ALSO COMES BETTER AND FASTER SHIPPING OPTIONS, AND MORE ITEMS WILL BE AVAILABLE FOR INTERNATIONAL SHIPPING AS WELL.
