Le site omely.store est-il sûr ?

This site appears to be a false store front that collects credit card info. I attempted to order a product, everything went smoothly until credit card data is entered. Then got message "credit card rejected". I entered a 2nd credit card, and got the same message. (Odd because my credit cards have rarely been rejected). Called the phone number on web site, but got odd voice mail that didn't indicate any affiliation with a business. I did not get a call back. Finally did some research of the company online and discovered that the "business" was started in Feb 2020 in the midst of COVID-19. In retrospect, it was especially odd that they appeared to have the product I was looking for for about half price and in stock when countless other site were out of stock.
