When they launched, they had 2 trucks which visited different parts of the country. Not sure if they've added any more, but they certainly don't have anything like full UK coverage - so, these offers are basically localised to specific locations rather than being open to everyone.
Is the item actually good? I can see cheaper pads by Ravpower and the likes.
I think the idea is its cheaper to load a truck with one item to sell in bulk so the one near me hits York Bradford and Leeds at 10, 2, and 6 and rotas the times and city's.
Oh is there only one truck? I figured all eligible locations got the same offer on the same day via multiple trucks. I stand corrected. Still pretty wasteful to send a truck all over the country to sell a single item.
Hate this treasure truck concept. Always miles away (I appreciate they can't be everywhere) and always during working hours. Seems too impractical too, driving multiple trucks around to sell one product only.
