I liked the old one but your new one is very nice. 
Maybe replace the free delivery for over £250 with something like. See them before you buy them. 
Just in case it puts people off with a lower budget. You and i know you have some amazing cheap fireworks but a casual browser?
And where you have welcome text maybe a featured video. 
The fact you have videos people can watch of the fireworks you sell is fantastic and should be promoted more. 
Later on I will Buzz everyone on my facebook to let them know, anyone else reading this should to lol, keep some firework sales in the acorn family so to speak. 
Must be an important period for you so good luck.
