S2 are the master importers and distributors for the UK. Sub distributors purchase from S2.
There are times when any one distributor may be holding stock that another doesn't though, though this is seldom a significant amount.
There are less challenges with customs but the simple truth most issues are usually down to the manufacturer (though hey, we're not perfect and make errors at times too!).
Most supply issues aren't even down to supply chain - at times they can be for other reasons. For instance:
CoolBlue had packaging issues for the EU which meant that they needed to be redesigned. This meant every order we had for CB was canceled between Feb and Jul. Planning ahead, we mitigated this by pro actively managing our levels. To be blunt, we lucked out in mitigating supply shortages with this during that time. More is now in transit.
There has been a massive Jojoba shortage due to the largest global supplier losing mass crops to freeze. This has affected some SolarOil supply and a couple other manicure SKUs.
But like I said, out of ALL the SKUs we carry, we have less than 1% out of stock. I also totally "get" that when that 1% covers something you need, you don't care - it isn't your problem. It may not even be our fault, but the reality is... IT IS! Nor am I being funny or sarcastic. I am flippen serious.
Anyhoo... just trying to provide some answers and some perspective.
Also... I have no real comment on the ransom thing... Maybe those are separate frustrations down in New Zealand (where Daisy_Hill seems to be). Here, there is no ransom. Its not like we send out letter to customers made out of letters cut from magazines saying "if you don't buy the Shellac, the bear is gonna get it". We believe we work hard to do our very best at representing what we believe are the best brands (we are not only CND) in the industry for the best value we can.
That doesn't mean to imply we are perfect, nor that our supply chain is perfect. Just to imply that is what we strive for and for the most part, I think we do ok, and look forward to doing that even better
HTHs
