WalMart app and InstaCart app

Wait!!!!  Did I lose you at "WalMart"?  Just hang on......hear me out.  I wanted to share my experience with the WalMart Pick up app and about reading about the InstaCart app in today's Billings Gazette article.  It got me thinking about a couple of things.  I struggle going into Walmart.  On top of that, I'm an impulse buyer.  My friend told me to try it.  This is what happened on my first purchase:
1) I stuck to my list - No impulse buying, which in turn, will help me stay on budget.  I can see my total as I add.
2) I don't have to drag my son into Walmart and try to shop...while I chase him.
3) I was more apt to order healthier options, because I did it at my leisure.
4) It is FAST!  You schedule a pick up time.  When your order is complete you "Check in" and tell them what color of vehicle you drive.  When I got there, there were 2 ladies there wait for me and loaded it in my vehicle.  So fast I had time to go home, put it away and go back to work.  BAM!!!!!

Now for the InstaCart......I haven't tried it, but basically its sort of Uber'ish.  $5.50 for delivery and here are the stores in Billings that will deliver to your house, work......whatever works for you.  Here are the stores they work with: 
CVS
Natural Grocers (they are a big supporter of them)
Albertsons
Costco

I may be late to the table with this info, but I was so excited how seamless it was and all the ways it could be a time saver for us all.
