The most cost-effective way to buy your Alensa contact lenses is to go with an economy pack. Packs come with both contact lenses and solutions, so you can combine your order into one, making shopping for contact lenses affordable and hassle-free. All in one multi-packs also come with a lens case, so you'll have everything you need. Economy packs work out a lot cheaper than buying items individually, so if you know you need to stick up, this is the way to do it.
