Well, then if you are choosing to make it something for customers only (and I do understand the desire to give back a bit extra to people who specifically support you), then I think the way you're doing it is nice.

As to being a good idea in general -

 

My personal input is that I like to see freebies being free for everyone equally, without preference to certain people or those who get there before others or who meet certain qualifications. 

:)
