PirateShip. Zero issues. They currently still are offering pre holiday label prices up to 21 pounds to most domestic locations. If there was an issue you could be talking to a person in 2 minutes. Fab customer service. You can pay your labels with a money back CC and just pay it off monthly and make money on the money you spend on shipping. Fab end of year tax info, It takes maybe 5 minutes to integrate your shop. It is FREE. It uploads your tracking to your Etsy orders and marks them shipped immediately upon purchase of the label. If you have more than one shop they are all there in one place. (I have 3 Etsy shops and Eba) I save time. money and aggravation. Seriously the best customer service I can remember ever having from a company.
