Yeah, returns in stores is what's done in Norway as well and while varying over time return rates have regularly been around 95%.
It's structured as a tax on single-use containers that retailers can buy themselves free from based on the proportion they can demonstrate returns for, coupled with a shared recycling scheme they can join.
In practice it means you can return containers wherever you can buy them, and most larger grocery stores have machines to handle returns. (In fact, the largest manufacturer of "reverse vending machines" for bottles is Norwegian TOMRA).
Recycling rates in places without bottle returns in stores basically shows that just having recycling centres or even curb-side recycling from home is woefully insufficient if you're serious about dealing with plastic waste.
