Stop in for a cup of coffee

Pretty much a wasted morning, running around looking for a side panel for my new cabinet. Nobody stocks oak plywood other than small pieces. What I need is 2ft x 7ft. Home Depot has end panels, but they are Beech. Lowes has some in Oak that are a little narrow, but I will probably do a 1/2” quarter round molding, so that’s OK. First Lowes had 4, but the grain was not the best on 3 and the other was damaged. Tried another store and they had none in stock. So thinking I might go to store on other side of Lancaster that shows 5 in stock tomorrow morning…
How thick you need?
