My PnP Bottles Review

My Checkers Sixty60 Review
Checkers Sixty60 Delivery – a review | Going Solar

Both orders I made had teething issues.
Process for managing issues on both apps / services is a bit lacking, as is driver training.
Overall the Checkers app is substantially better, although limited in the size of orders you can make (one motorbike load). The Checkers App substitution mechanism is highly non-optimal though, as it needs to be done on a item by item basis. I also couldn’t see any “specials” via the App. i.e Store Card specials. If you wanted to get those, you’d need to go to the shops in person. Not sure why that can’t be integrated into the App – they have your store card details already in there, tie it in! PnP had some specials in app, although similarly to Checkers, none of the PnP store card specials are listed.
