Just a heads up, n’at: some of the product descriptions on our site are created or assisted by AI. We do our best to make sure everything’s accurate, but every now and then the info might be a little off—kinda like tryin’ to find parking on the South Side on a Friday night.

Details like specs, features, pricing, or availability might not always be perfect, so yinz should double-check anything important before buyin’.

If yinz spot somethin’ that doesn’t look right, give us a shout and we’ll fix it up quicker than a Primanti’s sammich disappears at lunchtime.
