There are a few things that aren't adding up here as Scott mentioned.
1. The domain name was created only yesterday which seems fishy for a company who is planning a sale.
2. Upon viewing the source of iellosale.com it obfuscates the fact that it is actually loading a Wix website. This also seems odd for a company with an established web presence.
3. Iello uses a different company for it's shop on it's main website. (https://kibocommerce.com
) It doesn't make sense for them to set up a Wix website.
While it is possible that this is perfectly legitimate, I'd use caution as it seems quite odd at the moment.
