@Glennn,
No, you don't have to sign up for Prime to order from Amazon. Everybody and his uncle want to sign you up for a monthly charge, if I signed up for every $10 membership offered for just free shipping it would deplete every nickel I deposit into our accounts. By the way, depending on the shipping method/dates you choose your items might be shipped free anyway....you don't have to have Prime. Also, not everything you order actually arrives as quickly as it's promised, even when you use next day shipping and pay a boatload. Keep a close eye on delivery and if they don't deliver on time call and get the extra charge reversed.
I use Amazon when it suits me, sometimes it's the only place where you can buy a certain item....I needed an ironing board and didn't want the crappy ones they were selling in big box stores nor a really pricey model from Frontgate...I found one on Amazon that was sturdy and it was delivered almost within 24 hours....I don't know why it came so quickly...I didn't pay for overnight shipping and I wasn't a Prime member. I guess one was handy.
If you try Amazon again, make sure you are not just added to the Prime member list. It can be really useful especially when you want something that is usually out of stock in the stores. Personally, I don't want to drive to eight different places to buy a coffee maker.......however, sometimes you really need to see something in real life, not on the internet. Good luck and be careful of the marketing ploys, they can drain every nickel out of your account if you aren't careful.
