Amazon did that with an earlier version of their grocery delivery service. I assume the cost and logistics of managing and cleaning the bins just wasn’t worth it because their grocery service delivers in paper bags now.
One problem with the bins for normal items is that rarely will they be packed to the brim. I imagine the overall item density would drop significantly if they started using standardized bins instead of appropriately sized boxes for the items.
That service was really weird. They had a special arrangement with the post office.
They’d slice cold cuts in New Jersey, and have USPS bring it to upstate NY and deliver before 8AM. There would literally be a mail van with two orders in it.
OIC.
I will note like the other person though that I often get like "just one thing in a box that's clearly too big"
I used this service before it rolled out widely and these boxes were a mixed bag. On one hand they worked really well, they were essentially insulated hard totes with styrofoam lining and often had dry ice in them for anything that needed to be kept cold. On the other hand, I lived in an apartment, so storing 3-4 totes for a week or more was a real chore.
The funniest thing I remember though is that the totes weren't optimized for the size of some of the products available very well - if you put a frozen pizza in it, it sat diagonally, and without enough room to really put anything above or below it. You order four frozen pizzas, and you're allocating many cubic meters of apartment space for them until the next time you order.
Well, if there's one company on Earth that's both incentivized to find an algorithm to efficient pack stuff into their shipping bins and also well-financed enough to actually figure out a good linear or quadratic-time algorithm to do so, it's definitely Amazon.
And once they do so they'll have solved two big problems! :)
