Newclare class & Mirrors

Got a quote form Newclare Glass & Mirrors. *** Paid the 70% deposit & advised of payment on 20 Sept 2023 to find out on 26 Sept that their suppliers no longer running the special, and that it would be more expensive. I was not told / nor on the quote from Newclare Glass is in any way subject to their suppliers' stock/promotion levels. The request to honor their quote was just met with it will now cost about R2,000 more. I suppose this is what you get for supporting local business.
