AITA for changing my delivery address to mom’s house to not let my wife unboxing my packages?

We’re 34M & 33F, got married in 2022, living together since 5 years. My wife WFH (IT) and I work at a public department.
We’re childfree, the Government will take care of our retirement and hospital bills. So, we don’t have any big reason to save a lot of money…hence we spend like 50% of our combined income for upgrading our lifestyle, buying things for fun, travel, etc.
Each of us do like 20 orders/month. As I’m out of the house during the day, my wife usually receives my deliveries. The issue is, she unboxes my orders behind my back, even though I’ve told her not to. I know it sounds petty, but it ruins the unboxing experience for me. I love inspecting all the contents and packaging the way we received it, etc.
Although she roughly keeps them back in the place, that’s nowhere near as good as the original packaging. It’s not like I don’t trust her with the content, she’s a very little careless with items.
Once, she accidently threw away the manual of a gadget along with the packaging. I assumed that it didn’t come with a manual and spent my whole evening figuring out its functions.
I told her multiple times, still she opens them up out of curiosity. I can’t set the delivery location to my office as it’s a govt. building and nobody does that. Tired, I changed the address to my mom’s house, as she lives near my office, a distance low enough to visit her house even daily.
Mom has no issues with claiming my orders and never opens them. But now my wife is upset and accusing me of taking our personal matter out of the house. My mom isn’t tech savvy, she must’ve assumed that I get some discounts by getting things delivered at her doorstep. I haven’t told her the real reason why I did that.
