I think I've just discovered the ultimate shopping cart for us carless folks. The Go Up Trolley from Spanish company Playmarket is durable, practically indestructible, easy to maneuver, with a (very) large capacity main bag and a thermal pouch. And it folds down. If you think it looks like a stroller, you're not wrong. That's part of what makes the design so clever and useful:
The wheels are the unique aspect of this particular shopping cart: it has two fixed wheels in the back and two heavy swivel wheels in front (like a stroller), which make it super easy to maneuver in any direction regardless of how heavy you've packed it.
I don't own one of these carts myself, but I've heard rave reviews. The whole thing can hold up to 10.5 gallons, including the 2.5 gallon capacity in the front thermal bag. The main compartment liner is removable and washable (pretty essential when you're shlepping groceries!), while the front padded handlebar adjusts to three heights.
This is a serious shopping cart and priced that way ($150), so it's meant for people who walk their groceries multiple blocks and need something durable and sturdy, a cart that won't tip over when they hit a bump in the sidewalk or let go of the handle for a second.
Do you have this trolley? It's available in a few stateside stores, including Zabar's, The Container Store, and Bed, Bath, and Beyond:
