Not the cheapest for an iPhone SE prepaid, but if you have Verizon Prepaid, better than paying full price of $399 on Verizon's website.
I needed to replace my first gen Verizon prepaid iPhone SE. The iPhone SE 2020 showed no search results from the Walmart main page - maybe because it is oos online. I found the SKU from an expired SD deal and searched the SKU on Brickseek. It showed stock at a couple of stores and I had to drive over 20 miles to buy one. It was the price as listed on Brickseek, $249
When I activated the phone at Verizon, Verizon lowered my plan to $25 per month for service and 5GB of data. The $25 per month rate is after the 10 month loyalty discount and autopay. For what its worth, you still get 1 year free of Apple TV+ from Apple.
