Walgreens.com takes 25% off your contacts order with code JUNE25 at checkout. In addition to being 5% lower than the last discount we saw, all orders ship free. As an example, the pictured Biofinity Lenses drop from $41.99 to $31.49 per box. Personally, I am ordering these and saving over $18 per box off those ordered from the office. In fact, I always order them here and this beats the last deal by $2! Sales tax is charged in most states.
