The fact that you don't know you are lazy does not indicate the need for an apology but a self assessment. This is an open, internet forum and as such is sometimes plagued by trollers and scammers. Internet sites, to protect members from scammers, often enact legislation. If you look around on this website, you might see a section called forum rules. People who wish to become active, helpful, respected. valued members of a/this website would choose to open that and acquaint themselves with the community's expectations. If you were to do that, you would see rules regarding source discussion and the appropriate place for those discussions.

Failing to do that, you might also want to consider the lack of common sense when asking an open forum where to buy a product. Anyway, a fool and his money...
