Help me find some plinks!!

[sliceofcake]

Does anyone know where I can get some Plinks - they are little yellow balls that you drop down your waste disposal unit to de-grease it. Am using lemons just now but not as good.
Bought them in Lakeland ages ago, and can now only find them on Amazon.com. Where have they gone?

I used to get them at John Lewis.

Which reminds me - must Plink!

But did you know that finishing off your waste disposaling with the peel of an orange has almost the same effect?

ah did not think of John Lewis, will try there! thanks for orange tip, will try tomorrow, am sadly excited at new tip and potential plink supplier
