It would have to ship UPS Ground since its ammunition. Plus the additional fee to schedule a pickup it does not warrant the sale.
UPS charges a fee to pickup unlike USPS who does pickups during normal route times for free.
The UPS store clerks can not accept Ammunition over the counter, it must go to a UPS Customer Center. Cartridges/small arms(ammo) are not accepted in UPS drop boxes, The UPS Store Locations, or any 3rd party UPS Retailer, such as shipping stores, etc.
I have shipped larger amounts before with UPS and even with added profit for larger amounts, it really was not worth it on my end, I actually lost money on one deal just trying to keep my end of the deal up.
I will gladly ship on your dime if you want, if you pay actual shipping charges from 30117, plus the pickup fee, but on your end it would be cheaper probably to go to your local gun store, or even academy.
Unfortunately, unless you work at a location where the UPS driver comes everyday and can pickup, it is not cost effective to ship ammunition, especially in small batches.
