Talbots is running a promo for "Take an extra 50% off all markdowns".

There is a cashmere sweater I was eyeing and it had been marked down from $140 to $82. When I received that advert card I thought, wow $41, I'll jump. But when I went to order, the sweater was actually $70... 50% off original price, not "an extra" 50% off the first markdown.

I thought that was misleading advertising and told them so in a live chat. The person said she saw how that could be "misunderstood".

Now $70 isn't bad for a cashmere sweater, but I'm refusing to buy because I think they are being manipulative, trying to make things look like a better deal than they are.

Am I being too picky? How would you read that wording?
