Since I am a guy, I know NADA about this stuff.. That said, buying razor blades is like trying to play safe cracker half the time! They are locked up tighter than a bank in some stores. I was at a SDM one day and was looking at different razor blades. Every time you open the thing, it makes a loud noise. It was not long before I had about 3 staff members and one plain clothes person (pretty sure) hanging around the aisle. I was embarrassed so I got the one thing of blades and got out of there!
Not worth stealing razor blades though I have seen on tv that they are the most common thing stolen and usually in very large quantities and are sold at Flea Markets or online. Might be the same for the creams.
