Including something and calling it a "bonus" isn't much of a bonus if I can't USE it. It would be like you telling me that the rims/tires come balanced but the balancing is wrong. Again, it's a bonus since I didn't pay extra for it but it's no use to me if it's wrong (just for the record, i'm not saying that the tires are actually balanced wrong).
If i'm going to order from you and as a "bonus", you give me new lug nuts (something that I may have considered when making my purchase and may have swayed my decision to buying from you), I expect to get something that will work with my OEM equipment.
A lug nut that doesn't work with my lug wrench is not much use to me when i'm 100km from nowhere with a flat tire.
This has nothing to do with having the proper tools to install the package, I have these in my tool box, but my car does not have what is required to use what I was sent.
