Optics Planet has something weird about it. A few years ago I was looking at Hawke 8-32x Sidewinders on my iPad. At OP they showed $315. Everyplace else was $499. I figured that was a good deal and kept an eye on it for a couple weeks and the price was still $315 so I ordered one. I posted it on various bargain sections of airgun sites, told friends, etc. everyone said it showed $499 when they looked. I even sent the link from my iPad. So then I got to looking. On my other iPad, my wife's iPad, my iPhone, my wife's iPhone, my home computer, and my work computer the price was $499. My friend wanted one a few weeks later so I ordered one on my iPad, but the price had gone up to $329 (but with the 5% off coupon that came with my scope he got it for like $305). Eventually my iPad went to the $499 price. I wish I would have bought a dozen of them off my iPad now I look back.
