Rinse and Repeats

I will be honest I have mixed feelings about rinse and repeating deals more than once. I don't know why but I feel like I should give others the opportunity to get the deal too, and not clear a shelf. I personally get frustrated when on first day of the sale the items are all gone and I'm there fairly early. So I went in to my CVS today wanting to do the finish/electrosal tabs deal on DH's card because I had extra coupons, and wanted to roll it into more soda for DH. I went to the area where they store it and saw only 5 boxes (and this was the shelf completely full because there is not a large area to store them in that section). So I grabbed an assistant manager, and explained that I needed 7 to do the deal and told her the shelf was full but there are only 5. I don't want to clear the whole shelf can I order some for the friday delivery or do you have more in back? She told me they had  6 cases in back but were not allowed the floor space, so they've just been refilling the shelf with 5 more every time.  I asked if she could just get 7 from the back for me so I could leave the shelf in tact. She was awesome and said meet me at the register in 5 minutes :) So I did the deal again without making any of my fellow couponers suffer.....I know there are 2 others at least in my area because I see them from time to time.
