They all do it. Decleor had an amazing neck serum that I stockpiled then it was discontinued. When I'd used that up I found a JW Diamond range neck cream which REALLY made a difference, then it was discontinued. There was another brand that had great products then discontinued them (can't remember which one).
I never liked Gatineau but did order the TSV to try it as I hadn't bought it for so long I reasoned (ha ha) that they must have improved their products. We will see. It's for Christmas so I won't be using it until then.
