I have read elsewhere that this is only temporary while fireworks are on sale at the customer service desk, which would make a lot of sense. So, hopefully, normal service will resume some time next week.
We used Steve and his team at Tiddlywinks for my daughter's birthday party. They were great to deal with - friendly and reliable. The equipment plus delivery was reasonably priced and there was a wide range of options available. The kids had a brilliant time.
