Free repairs to your glasses or sunglasses. No matter hold old they are, or how many times your toddler went Godzilla on them. I'd even recommend custom tweaks when your first buy them.
Frames tend to slide off your face so get them adjusted. Costs additional for lenses if your prescription is medium strength. And sunglasses cost about twice as much. Can be busy
Ask a store rep how frames are currently arranged. Sometimes wider frames are closer to the front, other times they arrange by face shape (round, oval, square, etc).
Stupidly came on weekend for tightening, wait was super long... ended up shopping and buying new sets of glasses!!!! Honest, helpful, and efficient staff
Even if the store closes at 8pm, don't come in for anything substantial (adjustments, etc.) before 6:30pm, they'll just tell you to come back the next day.
