Isn't it kinda late to ask now that you've bought it already. For the future, anything is way, way cheaper online, I don't understand why GNC is so overpriced
Because they can be Ever go to an Albertsons/Safeway and they have the "name brand" stuff and the "store brand" stuff which is way cheaper? It's the same stuff (literally, produced in the same factories) as the name brand -- they just put it in new packages.
I'm not saying this is what GNC does - I'm saying that GNC is able to charge more because everyone knows their name. In reality, GNC makes so-so products that cost 40% more than elsewhere - I definitely suggest checking out the web or independent retailers.
