Great value and fast

I like buying from Walmart. The system works smoothly and I like the option of store pickup which is frequently available. In many cases I discovered the price to be better than other sources. I also love to have the option of not supporting Amazon.

My senior diaper delivery no matter the weather!

Walmart is like having a whole bunch of delivery ANGEL's that help me to live without worrying my family and friends to go to the grocery store for me AS Walmart already has my personal problem taking care of for me… thank you so much for your continued help and support.

I DID WRITE THIS BEFORE USE. BECAUSE IT WAS JUST DELIVERED TODAY. I'M HAPPY WITH THIS BRAND AND WITH THE SUDDEN AND FUTURE WEATHER CHANGES. THESE WILL BE FLYING OFF THE SHELF. I WAS VERY HAPPY TO AT LEAST GET ONE. SAFETY COMES FIRST. THANK YOU FOR HAVING THIS IN STOCK. I GOT THE EXTRA BATTERIES TOO. JUST IN CASE;-)
