Vons review: Product accessibility

I have been buying the vons store brand diet tonic water for many years and really love it.
Recently, my vons in tujunga, ca has moved it to the very top shelf.
I am 5 feet 1 inch tall!
How in the world am I supposed to reach the top shelf?
I have, a few times had to go find some one tall to get it for me.
It is not easy to actually find any one tall enough in this store.
I generally buy 8 to 10 bottles at a time.
This is very inconvenient for me.
Any suggestions?
(I have thought of bringing my own stool but that would be problematic for everyone)
