CHF 9 pretzels?!

This morning I went to the grocery store.  Almost every item has a bar code.  You have to weigh the produce and get a sticker that has a bar code with the total cost.  The only things that don't get bar codes are produce sold by the piece (ie some melons) and baked goods.  I picked up a couple of soft pretzels for a snack for me and lunch for LGG.  They were CHF 0.90 each.

When it was time to check out,  I noticed two items scanned for CHF 9 each.  I'm usually aware when I buy expensive items, so I asked the cashier which items were CFH 9.  It turns out she entered the wrong code.  Whew, that was close.  The pretzels are good, but not *that* good.
