I've made many purchases through woot.com and never had a problem. I generally buy their t-shirts from the derby. The sizing is pretty accurate and now they offer two different manufacturers of shirts so you can pick the one you want. The American Apparel tends to run a little smaller than the Standard. I have noticed, the Standard tends to draw up ever so slightly after washing, so I am more mindful of that when ordering now.
I've been a member of fubar.com for over 10 years now. I have made lifelong friends, several of which I have met in person. The site encourages social interaction with a leveling system. There is also fu-mafia for those that like games, as well as slots, and many other features on the site. I have made so many wonderful friends over the years, my life would be pretty boring without this site.
My favorite part of the Walmart site is the inventory checker that allows me to see if the product I'm looking for is available in my store. It's always right, and prices have yet to fail me. The site is easy to use, has a wishlist, and now even has 2 day shipping for free on many products. I've actually increased my usage of the Walmart site in the last month because of this. Love the updates.
So easy to use and find exactly what you're looking for. I check in weekly at a minimum to see new products. They send email coupons and reminders, without crossing the threshold of spam. Love this store, love the site.
I use Amazon not only for shopping, but for checking reviews on products before I buy elsewhere. The reviews are so helpful when determining if I'm making the right buy. There have been a lot of times I was going to buy a product, and Amazon helped me find a better one. Amazon Prime - totally worth it if you're considering it. I don't know how I'd shop now without my Amazon :)
I have been pleasantly surprised with how easy and useful the Indeed site is. My husband has been using it for quite some time, and I decided to give it a try. It's so easy to see exactly what is available in my area, how much it pays, the requirements, etc. Easy, no muss, no frills - just the information you need.
