Mask price exploitation ??

I found North 3ply surgical disposable face masks at the Builder Express store in Kenilworth Cape Town that are way over price compared to almost every other option I have found in other stores and online. A box of 50 for R650 that seems like price exploitation especially during this period. We have contacted them already concerning this matter at least two months ago. In the store the manager on duty told us that the cost price of the masks was R14 a mask so already you guys are apparently loosing money on the masks... and he said that they were made of a special material... that was the reason we were given for the high price.
