MSRP is meaningless, set at insane levels so every full-price retailer can claim to sell at 50% off MSRP while still charging 100% of the 'real' price.
Basic retail. Fun with compound fractions.
Pick any widely sold big brand name item you like, double its normal price, Google its MSRP and, surprise.
Most big brands are all over the net at 50-60% off MSRP, 24/365. Clymb may have a good sale price or not, but citing some % off MSRP is smoke because MSRP is smoke. It's only there to jumpstart some brain chemicals in the buyer.
'No refunds policy' is the retail version of hiring a limo to take a blind first date to a pricey restaurant. Might work out, but odds aren't good. Trying to cash out a 'buyer's regret' on a forum costs both money and the value of your time and energy.
Everyone's free to do as they please,YMMV. Nothing personal. I'm just saying that a 'no refunds' policy doesn't appeal to me.
