Didn't see this one posted and just got the e-mail from www.simplecontacts.com
"Now through 11:59 PM ET on 10/31/17, try out Simple Contacts and get $75 off your first contact lens order.
Use our online eye exam to renew your contact lens prescription, or upload a valid prescription and use code TREAT75 to get $75 off your order.
No minimum purchase required - just spooky savings on new contacts. It's that simple."
You can upload either your existing prescription or do their online exam that takes about 5-10 minutes and can vary from $10 -$30, so YMMV.
Got 6 months worth of contacts (Air Optix Night & Day) + the $10 Exam fee for $72.98 - all which will be reimbursed through my vision insurance.
Realistically you could upload an existing prescription or pay their $10 fee and get about 3 months + worth of contacts for $0 - $10 out of pocket.
