I don't know the answer to your question about other sales , but I would ask them if they would extend the PCE to you even if you didn't get it. I got the impression when I was in the FP store in my state (not near me so I haven't much experience there) that they would extend it even if you didn't have it if you knew enough to ask. But they won't volunteer it. Makes sense, I guess.
pming you too so you see this as you seem new... welcome to the forum
