Some stores like Wex that used to value regular and return customers have decided to go with a hardline of no haggling and no special treatment etc.
LCE is still really good to deal with and they give me decent offers from time to time.
Money is always an issue especially with an expensive hobby such as this. Especially in hard time such as these, I'd just say do whatever is best for you.
Events are on at various times in the year. There are also shows like the photography show in Birmingham for example that used to have good deals.
Of course with most of these events you need to travel too unless you are lucky to be very close by.
The event I visit annually is the Goodwood event that
LCE organises with Sony. Its normally in summer and its generally great place to go practice panning. They also have a model on set where you can try out their latest lenses and also practice your portraits. So I got to try out all the new glass here. Kinda makes it worth for me overall since I improve my photography a little, may be find a good deal or two and I get to try new gear for free.
Shows like the one in Birmingham doesn't offer me much outside the deals themselves so I personally avoid those but there are others that enjoy it and enjoy the networking etc.
