Wow, I got ripped off. Buyer beware at APE! On 6/8/20 I walked into APE and paid $278 for a gas valve I could have bought on Amazon for $66. This is the exact same valve except the one at amazon comes with a regulator!
Nice guys and very knowledgeable.
I expect to pay more for good service. I wouldn't have a problem with 100% more if they are advising me on what I need. But over 400% more? I don't think I'll ever trust these guys again. Never never trust this parts store for your appliance parts. Again, what a rip off.
