It appears that the Vipon Daily Deals email only displays about six sale items. Too view more, you have to go to Vipon.com. Once there you can try a search to narrow down the items. For example, search on "Flashlights."
I have very little experience actually navigating Vipon. Others may want to chime in with more tips. Seems like there are only a limited number of available coupons for each item.
Also ordered one of these at 1/2 price via Vipon deal: https://www.amazon.com/BIBTIM. Always hard to find a e-switch zoomie, specially cheap one. I know this form factor - it's made cheap for sure, but for under $10, it's an ok deal, usually.
Reading the reviews, it all mostly positive, but looks like the typical inflated lumens claim, probably low or under amps. Looks like decent quality from the pics.
Everyone seems to think 600 lumen is about the average. I can compare it to some other lights once I get it with my lux meter. Once I get it maybe it will be easy to disassemble and mod. Looks similar to a Nitecore I have but I think the body on this one is aluminum. Maybe.
