Shrekfeet, The next lesson in prior preparedness may not be as easily solved. Be sure to have spare kit available before the bees consider it to be swarming season and you have to split your colony into two.
Have a good season and love your bees. Consider applying for a Booker cash and carry card, as a bee keeper. When asked for the name of your business, use your own name.
I bought sugar from Booker's on Friday at £9.99 for 15kg (1kg x 15) which is 67p per kg.
There are several Booker warehouse outlets in Hampshire, so likely to one near to your largest town. I actually bought 60kg.
