Where can you buy a microscope at a store you don't like online alternatives?

That will vary on what country you reside. In the United States you will find a microscope set at a major outlet like ToysRus. Expect to have a pretty basic microscope. If you are more serious, check with local medical supply stores for your area. High schools' science teachers/labs could give you insite on this also. Check at the hospital laboratory for another lead on microscopes and their purchase.
