I think that this thread is pretty much closed

Because they probably are going to start filming the final tomorrow, and it's highly unlikely we'll get any photos from that...
But to round of this thread, putting this near the end, so it's easy to find when the spoilers thread comes into existence this Autumn, here is a summary of the tasks...
Task 1 - Selling flowers and coffee
Task 2 - A male subteam were spotted, possible doing market research for a product design task.
Task 3 - Selling incense sticks and candles at St. Pauls
Task 4 - Literally no sightings.
Task 5 - Were seen in Canterbury, Rochester and at Folly Bridge - god knows what they were doing.
Task 6 - Seen in London a few times - Covent Garden, Camden Town etc. (20th May)
Task 7 - No sightings (Perhaps an abroad task, because there is such a large gap...)
Task 8 - Selling products at Bath and West Show
Task 9 - Very likely to be negotiation task.
Task 10 - Talk of filming in offices, waitrose and a 'store'. Karren and her team seen outside Apollo studios - whether they were working in the studios is unknown. I think this is a selling task of some sort - perhaps like the Ready Meals and Biscuits task.
And here's my document showing some of the candidates... (and a few spoilers)
