Hello. I have iPhone 6 and it's on iOS 12.5.8

Is there a way to download/sideload Walmart app on the phone? App store keeps saying, need 16.0 or later to download the app. TIA

I placed the pre-order of CR back in April. 2x CR ETBs, 2x BB and 1 Display Box.
I get my order last week but instead of 2, they only send me 1 booster bundle. I have opened the support ticket and they asked me to provide them the pictures of the shipping box showing tracking or order number and the picture of the products inside the box. So, I sent them 4 photos and now its been 4 days since I heard back from support. Has anyone experienced anything like this before? If they don't reply in next 3-4 days, should I just call my bank for refund?

I am planning on keeping some of my ETBs for longer period and ordered some Acrylic from Ebay. My question/concern: Are ETBs safe in these boxes for 4-5 years? I am planning on keeping them in laundry room where we only turn on light once or maybe twice a week and there's no sunlight whatsoever. Would humidity play a part for keeping the ETBs in Acrylic boxes for 4-5 years? what are yours thoughts? TIA
