Good point, I agree with you that it looks like a lot of trouble. However my wife does this all the time, it's a women thing, I guess. She fills out these rebates and mails they in and in a few weeks, the checks come. Sometimes she has to have them mailed to other addresses. Again, no problem.
Now as for pointing this out to my customers. Yes I think that would be a good thing to do. Yes it may take a little effort to get this, but for a $100 in gas, it is worth it.
