Tell me about 'Google Express' (30% off 1st order for new customers deal)

[steve...]

Any downside for using it? Is it free? Does it work at any online retailer?

Saw the 30% off deal at Slickdeals.

Google Express offers New Customers: 30% Off (Maximum of $30 Discount) on the Google Express App (iOS or Android) when you apply promo code APPSAVE30 during checkout. Shipping is free on orders of $35+ (may vary by store).

Note, must purchase via the Google Express App to apply the code. Discount valid on your first order only.

Ok... looks like you need to order from items only on the Google Express website. After a brief scan of items/merchants, prices didn't look so good, even after 30% off — IMHO.

Yep prices are high
