... about "more than one way".
Of course it depends on your knowledge level of the program, but also on what you intend to do with the worksheet.
For example, in this instance a new column with a formula with something like =IF(B2=C2,"Same","") would allow you to count the "sames" and know how many you sell at the asked price. Or instead of "Same" you could simply write the formula =B2-C2 which would allow to know how much money you are making (or losing). The possibilities are almost endless and that's the fun of it.
