This is a photo of a working switch: The purple arrow points at the contact area that may require cleaning opposite side as well. You do not necessarily have to remove the leaf spring to do this I recommend leaving it in place. The green arrows point at the notches mentioned in the article linked above. The following switches will not work as the leaf spring is not positioned correctly in one of the notches: This one is particularly tricky as it is impossible to see the problem with the naked eye it looks fine but should be in the notch above.

Delivery costs many times more than the items themselves Even from eBay? Whereabouts do you live? Perhaps a friend has a broken one? It may be possible to repair them. Those little switches have a snap fit cover, and can be opened up. At this point, plug in the mouse and test the switch. If not, try to push on it in such a way that the problem happens.
After you have attempted to fix the switch, you will be able to test it again without re-assembling the whole mouse. Unplug the mouse now. The switches come in a variety of different designs, but they are fairly similar. You might find it easier to remove the spring from the switch first. Place it on a table, and squash it slightly with your finger.
Not too much. Better to err on the side of caution. Then put the spring back in the switch. Test it again now. If it still bounces, then you might need to flatten the spring a little more. Tear off a thin 5mm wide strip of J-Cloth or similar. Apply a little abrasive cleaner like CIF to it. Thread it through the switch and pull it back and forth to rub away any dirt from the contacts. Tear off another strip, and soak it in methylated spirits or pure alcohol. Use this to clean off the abrasive cleaner.
Test the switch again.
