Buy now or wait a bit longer?

I've been thinking of getting a dash cam for a long time and a freak incident I had last week prompted me to into one even more intensively. I've been looking at the VIOFO A119 Mini 2 or the A229 duo (still haven't made up my mind).

I know they are currently running promos on their website, but I was wondering if it's better to wait a month or two for their spring sale for even lower prices?
