I had seen this and several other similar threads when contemplating how to build my front false wall, but when visiting Home Depot, Lowe's, etc., I couldn't tell which of the many choices of lumber Big was talking about. So, a few weeks ago I set out on a mission to sort this out. Now I'm sharing the intel so others don't have to go through the same process! It sounds simple enough, but these stores stock massive amounts of product that look similar (at least to my non-construction-worker eyes).
First up, Home Depot. Walk over to the lumber section and look for this:
Here are some of the corresponding product SKUs you want to focus on:
You will see a label on the wood products that looks like this one. Choose your width, and that's how you know you've found the correct item.
Over at Lowe's, the stack looked like this:
And their SKU's/prices:
Note Lowe's calls the same product "Primed Pine," while Home Depot refers to it as, "Primed FJ Board." I found HD to be slightly more expensive for some lengths, and on par with Lowe's for others. I ultimately purchased from HD out of convenience.
