Do you think It's safe to shop at this website?

Ok i need to buy some SR626SW watch batteries and i found the best price at this site but when i click on the check out icon a window poped up and says that the security certificate could be expired or invalid.

has anyone ever purchased anything from this site before? do you guys think it’s safe to buy from this site with my credit card?

thanks for your time

Verify the certificate and email the certificate authority (the one who distributed the certificate) about the company.

I’ve never even heard of this site. There’s nothing on ebay?
