My latest shopping experience was quite nice, Tuesday evening I ordered flea medication for my cats plus a couple add-on items I needed and selected free super-saver shipping. When I got the notification Friday that it had shipped I noticed that it promised delivery Sunday by 8 p.m. I thought surely that must be in error, I thought Amazon's Sunday delivery deal with the USPS was only for Prime customers but, lol and behold, my package arrived today at 1:30 p.m. That makes it four days and 20 hours from order time (Tuesday 5:30 p.m.) to delivery (Sunday 1:30 p.m.), pretty good for free shipping I'd say!
