Rebates from ASUS

I just bought a graphics card from ASUS, which (in case you don't know) is a very reputable maker of computers and computer components. They offer a rebate for certain items purchased in January 2012. After clicking through a fairly complicated form, I reached the following page, which I reproduce here in part:

o No-Wait
Choose our No-Wait-Rebate service. We will mail your Rebate payment via 1st class mail within 5-7 business days from the date of approval of your claim for a small fee of $1.00 which will be deducted from your Rebate payment.

In other words, for the modest fee of $1.00, I can have my rebate in about a week after it's approved. Otherwise I will wait about 2 and a half months. Why does ASUS do this? Why should a reputable company appear to be chiselers, all for about 15 cents, which is the interest on my rebate ($15.00) for 10 weeks.
