Random price increases the reason they only get 3 stars

Although the salon I use in the Garden Centre has expert stylists and very friendly staff, the company has a habit of randomly increasing their costs which is very annoying. Recently they ran a special of a wash, blow dry, and flat iron for R200.00, which then became R220.00 then R230.00 and now if you want the flat iron included it is R330.00. This senseless price jumping is the reason I left last time after using them for decades.
