Over four months ago I purchased O2 Optix contacts from Coastal Contacts. I received the correct contacts in the mail within about a week of purchase.  
 
At the time Coastal Contacts was offering a $60 rebate, so I filled out the form and mailed it in about 14 weeks ago. The rebate form explicitly states that the rebate would be issued in 6-8 weeks. I have called Coastal Contacts three times and emailed them once and I get horrible customer service.  
- During the first call (3-4 weeks ago) they told me that the rebate form was indeed received by them and that they would email me within a day to let me know what was going on; I got no such email.  
- About a week later (over two weeks ago) I called again and was told that the rebate was approved by them and that it was "awaiting signature" and was probably already in the mail to me. I waited and waited and never got the rebate.  
- This past Monday (3 days ago) I emailed Coastal Contacts to complain and they have yet to write back even though their website says that they respond to emails within 24 hours.  
- Today I called and they told me that they could not listen to my complaint because they were experiencing a high call volume due to the upcoming Halloween holiday (go figure?)  
 
So, what it boils down to is that do not expect to receive a rebate from Coastal Contacts and do not expect any customer service - because they do not have any.  
 
In addition, their website appears to be American, but it is not. They charge your credit card from Canada which can produce a foreign transaction fee on your credit card bill. Their website has no disclaimer saying that this might happen and there is no indication on their website that they are located outside of the United States.

So I paid my total amount due of $336.11 before the due date for my focus dailies. A couple of days later I saw an additional $10.08 charge on my credit card. The description was "International Transaction Fee." I was surprised because I thought this company operates in Blaine, WA! I contacted the company to see if they would give me a refund, if not i'll just call my credit card company and tell them that it was a fraudelent charge.  
This is my first time ordering from Coastal Contacts and will be the last. I usually get my contacts from VisionDirect.com and NEVER had any problems at all.

They sent us an order without us confirming the order. They shipped it with a bill. We didn't want the contacts in the first place. Avoid entering any personal information at their web site.

Terrible web site. There is no confirmation step. And no credit card needed - just an invoice immediately after choosing your doctor.  
 
I used this site because my doctor has moved and I don't have time to find another one. I still found my doctor at his old address in the list so chose that.  
 
I now have no idea if I will receive my contacts or not, because I don't know if they will be able to contact him, or if they'll even try.  
 
I'll post back here once I get a result.
