On 09-Jul-2020 the supplier responded:
Good morning, Thank you for taking the time to leave feedback.
I am very sorry about this stocking error, we sell across a range of channels including our website, eBay, Amazon, our shop and over the telephone so occasionally stocking levels are incorrect due to the system taking a moment to update.
However I completely agree, it should not have taken us 5 days to contact you regarding this and so we will be looking at our processes moving forward.
Apologies once again for this issue.
Best wishes,
Laurie

Good product at a value price, easier to use than the butyl rubber ones. Having the underlay come with it was a bonus although we also purchased a thicker one to go in the pond as well to be on the safe side. Very pleased.
