I wouldve just had them change the shipping address, that sort of album / canvas is the stuff you as parents will be cackling over for decades to come :D
Unfortunately it was too late to change the address by the time I discovered it, but we, uh, actually did order our own copy (from a much cheaper photo place) and it's currently hanging on the wall in our kitchen.
Assuming it doesn't completely blank out or disintegrate by then.
When it comes to durability, I have little trust in companies today, and the quality of techniques and materials they use - not in a hyper-optimized economy we have now. Especially when we're talking about prints ordered through a button in an app made by an advertising company, one that wants you to stay subscribed to their digital playground (instead of focusing on physical ownership of media, such as photo albums), one "products" (services, really) have a half-life on the same order as digital print/ad shops.
Nah, the very presence of this "feature" actually pushed me away from Google Photos. In a perfect world, it would make sense. In the real world, it's just first-party user interface spam.
