Sales Confusion

I went to Checkers Cape Gate today to buy Epimax plus cream which clearly stated on the sales catalogue "Epi-Max skin cream assorted each R54.99.The lady told me that the Epi-Max plus is not on sale and I showed the catalogue to her and told her that it states assorted.I had to leave the shop with a red face and empty handed.Im really upset because it's not my fault that they did not state excluding Epi-Max plus.It just really frustrates me when unnecessary confusion is created.
