A big part of Lens.com's sales/marketing pitch is their rebates and a $160 rebate is substantial. I completed the appropriate form and mailed in my UPC codes. It's been almost six months and no $160 Visa card rebate. I looked up my rebate status on their website & it's been processed all the way up to the "mailed out" step. Delays are sited due to supply chain issues. Really? Is there actually a shortage of plastic credit cards or is this just an excuse?
