Supermarket Sweep also did that during the original series (despite on the end credits saying where they came from). The confusing bit was, was it product placement or not because of that?

Product Placement wasn't a thing in this country TV wise until 2011. So that answers your question. No it wasn't.

Although it was deeply ironic that you could watch any major film you care to mention (or some high profile US import) on the telly and have the concept shoved down your throat. But the original film makers benefited, not the broadcaster so... but anyway I digress.

There was a difference between "thanks to Supermarket A" as opposed to "Bought to you by/courtesty of Supermarket A".
