My first order with instacart, was a small "test" order, and it went well, and left me feeling like someone had mastered shop & drop, and turned it into a big business.
My second order was a minor train wreck, but survivable, if one has the time and patience to connect on the phone with customer service, and spend a few hours getting things straightened out.
My third order was a complete disaster, and what did finally, after 19 hours, get shopped and dropped, never appeared at my door, until 5:30 AM the next day, in a neighbor's arm's, as she told me when she opened her door, to leave for work, it was sitting there. Of course all the refrigerated and frozen goods had ruined. It was then I said I'd never do instacart again. But instacart had refunded my money, and gave me a $20 credit to my account, plus one free delivery.
A month went by, BTW I am disabled, and can not physically go to the stores myself, and this day I thought a frozen pizza would be nice, so I thought I would give instacart a chance to redeem itself, and I used the $20 credit, to order 4 Jack's frozen pizzas. Of course I added a couple loaves of bread, some potatoes, and cleaning supplies.
Well low and behold - I GOT SCREWED! AGAIN! It's obvious I'm not getting my money back this time, That $20 credit and a free delivery was obviously a set-up and I took the bait! Let me leave you with this warning - instacart is fantastic for your first order, but don't let them sucker you in. It is the only time you will be giving them 5 stars, from then on out, you're screwed! And instacart will play you to the MAX! Keep your money, and your financial information. Don't be the fool I was!
