Best, Cheapest way to mail a purse?

• I need to mail a purse 11inches long, 11inches height, about 3-4inches wide (can flatten though to 1-2inches). I need an estimated on the best, cheapest way to ship it because I know if I stuff it in an envelope or box it's going to cost like $12 at least, How much are the large flat rate boxes? Also, is parcel post cheaper than first class?

• Answer:

  USPS is reliable and say the best way to ship a purse.
