GA Arms has Remington Reduced Recoil Buckshot and Slugs on close-out for 9.95/25. This is not listed on the website, but you can call 1-800-624-6861 to order. (If anyone else orders some, perhaps you can ask the salesperson for the item #, and post it.)
I believe their hours are 8 or 9 to 5 Eastern.
