This is one of the worst sellers of dog supplies online. AVOID BUYING ANYTHING FROM THEM. I ordered 74 tiny puppy collars to identify newborn pups. Less than 2 ozs each! They charged me extra weight charges for 59 POUNDS! 74 collars DO NOT WEIGH 59 POUNDS! Since they can't correct their shipping charges, I cancelled the order and will get them elsewhere. This business is totally corrupt!
