This site dedicates a specific section directly to this warning: SodaPeak has no authorized retail or marketplace channel that we could find.
Amazon, Walmart, eBay or similar platforms — this site is direct that any listing on these would be a third party reselling at a markup or worse, sitting entirely outside the manufacturer's guarantee.
This site states it plainly: buy from the official website or don't buy at all — that's what keeps the 60-day guarantee enforceable, per this site's own framing.
Reviewed against a documented methodology. 60-day money-back guarantee, official site only.
