I booked two General Admission tickets and a camping permit for BSJ from Just Tickets about ten days ago and there was no problem there either.
Haven't recieved them yet, but Just Tickets have always been reliable before so I don't doubt I will.
How much did they charge you for them? The face value of the tickets will be €55 for the General Admission and €46 for the BSJ but it looks to me like they are Charging £55 for the GA and £53 for the BSJ. So the cost looks like it £163. €156 worth of Tickets for £163 sounds like a bad deal to me.

It's not a great deal as they charged me a total of £170 including Special Delivery. But, to be fair, I only decided to go in April and I was happy to get any camping permit at all at this late date.
Might well consider booking via the ACO for next year though.
