Donn not buy anything from the online store, Springs4garagedoors.com or doorswholesale.com. I recently ordered some springs from my garage door and it took over a week before they shipped and another 7 days in transit. The website says "ships in 2 days GUARANTEED". Meanwhile, my pregnant wife is loading and unloading her care in the rain. I tried to reach them via email, twice and on their toll free number at least 3 times and nobody ever returned emails or voicemails. After waiting about 8 days I decided to contact a local garage door repair company that came out and replaced the springs and repaired the door within 3 hours of my call. Springs4garagedoors.com finally returned an email a week after I returned the springs and told me that I got what I ordered and they wouldn't refund my money. I offered to pay the return freight and everything. I would recommend not doing business with this company if you like customer service or any type of timely response. I have no idea of the quality of the merchandise, because it is still in the original packaging and unused, but to me Customer Service is a huge reason of why I shop at certain stores.
