cindala- If the "my Avis" online coupon is still running, and I can't see what it wouldn't be, you should be able to combine with any other code. Last year they said that I could combine it with any other discounts that I used. Why don't you call customer service first and ask if they still have the online coupon and if you can combine it. I wouldn't waste my time with the regular phone reps, they don't seem to know many answers. Just a quick note, your on-line coupon is applied when you return the car, not at the counter. My pick-up ticket at the counter was 25.00 higher then I thought it would be, and the rep. told me it would be adjusted at the time of drop off, it was, so don't worry about it if see your coupon was not applied at pick-up.
