Straps prices are fucking insane

I know it's not a new problem, but I was shocked nevertheless. On a Canary Island I managed to buy my dream Omega Aqua Terra in a very good price. On a bracelet. They didn't have, and couldn't order a dedicated silicon strap.

When I contacted my domestic (Polish) Omega dept., it turned out that rubber trap + clasp + those things that make it look like integrated strap cost almost a 1k euro. I expected a high price tag. But this is a bit too much. I like the integrated look that the original has, that's why I don't want to go into Hirsh. Do you have any alternatives? Or am I sentenced to blow almost all my discount into this ripoff?
