Costo Online Store Recensioni 

DON'T BUY FROM THIS SITE
For sure a scam. I tried to order items with multiple attempts at checking out (with different credit cards), and each time the card was "declined." Pretty sure they stole my card information. Lesson learned. Now I have to get new account numbers. After reading the reviews on the web, it seems like this site is new and popped up recently. What's worse, they did this during this whole coronavirus epidemic when they knew people would be trying to buy masks. Disgusting people.

Like the others -- tried to buy n95 masks. Entered CC info -- was rejected. I'm canceling my card now.

SCAMMERS - acting like the have N95 MASKS!
REPORTED TO FRAUD UNIT - REPORTED TO COSTCO and REPORTED TO WASHINGTON --- they found them!!!
just scammers and hackers collecting bank and credit card info from innocent people - change you user id and password ---asap!!!

Fraudulent. Do not plug in your personal information and credit card.

Fraudulent company. Check the spelling- these thieves are Costo not Costco & the address they are using is a shoe store. Do not put your info in!!! They are credit card thieves.

I tried to make a purchase from Costo thinking it's a Costco store. I put all my info and a credit card and it kept saying Your card was declined. I was stupid enough to put my full info from 2 other cards thinking it's an error on my part. Now I have to cancel all 3 cards....lesson learned

I was trying to buy something online and thought I was purchasing something from Costco. However, the domain was actually costo.store I never received my login info. I added my credit card info and tried to purchase and it keeps failing. I think they may be a fraudulent website stealing credit cards. I researched the domain and it was only opened a few days ago.
