Is it usual practice for big-name hydroponic suppliers to send you catalogs in the mail after you order from them? Even using a safe address doesn't this raise certain concerns? I've never come across this happening to anyone before so I figured I would say something about it. If it would benefit anyone to know the name of the company I'll be glad to note it but if it's a usual practice and my fault for not knowing to immediately request my name be taken off anything promotional they might or might not (!!!) be sending, I don't want to give anyone a bad rep.
Edit: There is a "customer ID number" on the back of the catalog. Ugh.
