I usually order the cheapest shipping. I've done Egg Saver twice I think and got both in at least 4 days. Otherwise it's just 3 day for me. I ordered 3 day once and it upgraded me to 2 day for no extra charge, I was kinda surprised when it got here so fast.
I think Egg Saver is just for small things. My 2 Egg Saver shipped orders were a stick of RAM, and a flash memory card for my phone. Both came shipped in a padded envelope. I really like the free shipping though. Just ordered a digital camera and I only had to pay the price of the camera, $109.99. Cheaper than Walmart, no tax, and free shipping, can't beat that. Only bad thing is waiting a couple days, but for about $60 saved, it's not bad. I'd never pay a premium for 1 day shipping, that's just stupid unless you're in absolute dire need of the product, and then it'd just be cheaper to pick up at a store...
Geez, I wonder why it would take that long... I ordered my camera on Friday, the 26th, with 3 day shipping and the estimated delivery is the 30th... Almost seems like 2 day shipping.
