I ship using priority flat rate boxes to ensure my soaps arrive with the least damage possible and also to save them from overheating in this summer heat, as I live in Las Vegas. Depending on the size of the soaps I can usually fit 4 bars of soap in the small flat rate box. Any shipping overage over a $1.00 will be refunded right back to you. I ship out Monday-Thursday, and as soon as I receive payment.
