Usofferstore 

I located a product on usofferstore.com that was not only available (where I couldn't find it available anywhere else), but also at a lower price than the out-of-stock sites. Suspicious, I searched for reviews and came across all the reviews here. Thanks for the alerts.

As further confirmation, I did a "whois" search on the usofferstore.com domain and found it was only created on 9/16/2020. THAT alone is a red flag!!

SCAM!
I tried to shop at usofferstore.com
It appeared to be related to Walmart -- but declined my credit card AFTER I entered all the info., I then tried my bank debit card, and when it was also declined, I got suspicious and nervous.
The website had similar Walmart help center page, etc., but nowhere could I get assistance, and after calls to Wallmart store and online people, I got no help or interest in figuring out if usofferstore was scam, so I figure it is not legitimately related to Walmart as it presented itself to be.

BEWARE: A site meant to steal your credit card information. My credit card information was stolen and fraudulent charges appeared the same day.

BEWARE: A site meant to steal your credit card information. They offer deals that are below other web sites to lure you in and when you input your credit card info. they reject the transaction and steal information. I now have fraudulent charges appearing on my credit card and I have to cancel the card and get a new card. Unfortunately they appear on Price Comparison site on Google and that led me to their site. Do not trust price comparison sites!!
Always check their physical location(address) and do a Google serach. I can not find their address which should have given me also the clue.

Scam site.. stole my credit cards. I tried a couple different cards to buy something (only website I did this on with more than 1 card - each time being declined) and all my credits cards I used were subsequently used on other websites not by me to purchase stolen goods.

SCAM. Do not try to put in your credit card info!!! I got suckered!!! BEWAREEEEEE

This is a scam site that is trying to steal credit cards.
I got scammed while looking to buy some coffee. The website rejected my card, so I tried another card which was rejected as well.
I suspected that something was wrong to I froze my cards. After a few days I started receiving alerts about rejected attempts of card charges.

The site is lowkey scam that makes people link their credit cards and then sell the information from it to underground web criminals. DO NOT GIVE YOUR INFORMATION! And if you did cancel it immediately

Yep, I got scammed too. Put in my credit card when payment info came up, hit submit and it came back 'Credit card declined, use another card'. I was perplexed but put another card info in and same response...card declined. I knew I had money in both accounts, called my banks to check my balances and then tried to call the number listed on this company's site....no answer. I tried to email them. At this point I realized something was wrong and did some digging on this 'company' and found this site where other people reported similar stories. I called both credit card companies and canceled the cards, thankfully they hadn't done any damage yet. This company's website looked so legit and I always check to make sure the 'lock icon' at the top of a companies' website is there. I even did a search to see what buyer's reviews are and they supposedly had a 4 out of 5 rating. I dug a little more and found that USofferstore's website is exactly, word for word, picture for picture the same as Walmart.com. They just substituted their name for Walmart. They even lifted Walmart's reviews. I plan on calling the Better Business Bureau and leaving a complaint also. The BBB said 'This business' profile is being updated' and there were no customer complaints. I think they are so new their scam hasn't caught up with them yet.

I should have realized the prices were too good to be real. Same thing happened to me they took my credit card information, then said it wasn’t approved, to enter another card. At this point I was skeptical as to this site’s validity. You’ve been warned, don’t shop this site, scam!

The site will not let you pay after getting your credit card information. I tried a few cards and it always says the card is declined. They are looking for card numbers. A month later my credit card statements came in. ALL the card numbers I gave them were used fraudulently to buy things. Gun/ammo/hunting items and gaming items and airline tickets. DO NOT give any information on this site. you will get bogus charges for doing so.

Fake website!
Beware! This is a FAKE website! It is set up to "reject" your payment, yet at the same time, harvest your card information. This rejection makes you believe that your own financial institution rejected the sale and to "try another card"...

The phone number listed on the site is fake, and the one that they give you in e-mail correspondence is set up to be ALWAYS busy... even at 2am. The address listed under "contact us" doesn't exist either.

A week later, someone tried to make a fraudulent purchase on a card I used... You have been warned!
