I hate having to give a place one star just to rate them. Extremely disappointed with my experience here. I bought a groupon for $45 for this place which clearly states in the groupon verbatim: "The amount paid WILL NEVER EXPIRE and must continue to be honored by the merchant after the promotional value expires. The amount paid may be applied toward any goods or services offered by the merchant if the promotion is no longer available.". They refused me goods as I did not need services. The guy told me "I don't need your business." Fortunately for me there is a bike shop about every third block so I'm more then happy to not give you my business.
Follow up to Pat's comment: NOWHERE in my voucher does it say can only be used for services, not retail products. What it does say, again, verbatim: The amount paid may be applied toward any goods or services offered by the merchant if the promotion is no longer available. You can follow up with whomever you like but there are no misunderstandings on this end, just an irritated would be customer.
