Is there a difference between perfume bought at a drug store vs. a department store?

Is there an ingredient difference in the two? I've heard that the drug stores usually sell perfume cheaper because they add more alcohol to it?Is there a difference between perfume bought at a drug store vs. a department store?
You can now buy name brand perfumes that you would buy in the department stores. The perfume in the drugstores that are name brand are usually in a very smaller bottle, but it's still the same brand. They only carry certain name brands in the drugstores. If you want more for your money then you would need to go to the department store.Is there a difference between perfume bought at a drug store vs. a department store?
Well I don't know about adding more alcohol but the drugstore is cheaper because they sell a lot of no name brands vs. when you go in Macy's etc., you're paying for the name, not what's inside the bottle.
if they're the same brand then i'm pretty sure that they have the same ingredients in them.
Well there's cologne and perfume. Cologne has a higher alcohol content and doesn't have as concentrated a scent as perfume. Check the label and the size--you can buy the same product at both places--drugstores might be cheaper though.
