USPS now charges for the dimensions of the box plus the zip and weight, The good thing is I price my things so low that helps with the darn  USPS rates sadly sometimes the shipping is close to the cost of the item, know you got the item at a great price.. Shipping is shipping I have no control  I will always check the prices difference between snail mail and priority I am finding a lot of the times priority is the same or even a few cents less so weird? So in that case it will go priority.

thanks for looking
