7.5lb bucket of Isopure No Carb is $76.99 and will last me a month. GNC is regularly selling this for over $100 but it's on sale for $90
I think the point is to find an online retailer in your area. If it's something that can be delivered in 1-2 days, I'm sure it will be cheaper than in stores, unless there is a huge sale.
Do they have a walmart there in Greece? Walmart (by me) sells creatine and l-glutamine, as well as other nutritional supplements.
