Reading the google FAQ earlier one of the questions was whether it's better to use underscore or hyphen for filenames. The answer is that this changes month by month.

It seems to me that something like "buy" or "sales" could also be fickle because really they mean the same thing.

Like what others have suggested in the post, online I'd do the following:
1) overture/webtracker search results for previous months.
2) Adwords on the two terms
**These two should give you a good indication of which is the more popular term currently
3) I'd also check what competitors are using. Maybe "buy" is more searched but "sales" is underexploited and would be an easy target.
4) Also what you can do is look at what offline advertising mediums such as magazines, tv, radio etc. are currently using. If someone has just listened to a radio advertisement to "Buy xyz widgets from companyx now cheaper than ever!", guess which term they are more likely to search out.
