I like that AMM has multiple shipping methods for my customers. It's great because sometimes they want something shipped via USPS but other times UPS or FEDEX are better options! Sometimes there can be delays in processing orders when using different carriers (due do some companies not being able to ship certain items at once). Make sure everyone involved knows how this software works so as far as customer service goes things will go smoothly! You'll have peace of mind knowing all logistics of shipments are taken care off by ASM.
