I believe the “rig” is that victron sets all prices and resellers (no such thing as buying directly from victron from Amazon) pass along the set price (maybe mark up a bit here or there if they can). The resellers only get a kick back/paid from victron if the item is sold at an agreed rateWho exactly is giving these price discounts? I checked currentconnected.com and solar-electric.com and didn't see at a glance any price reduction.
Thus if a seller has stock (extra overhead to hold inventory) and victron lowers the price there’s no loss on the reseller.
I think this is very similar to big box power tool sales. Low risk for the reseller (especially for something that grew legs and walked off) when prices change and sales are a flurry.
Either way I had my eye on a 150/35 for a long time and I’m this this this close to pulling the trigger.
I’d love it if Lynx and MPII had similar discounts (I did see 24/3000 MPII was slightly discounted)
