I went to Booker (wholesaler) today for the first time as I'm doing a bit of catering for family events. But most of it was more expensive than Tesco (the parent company of Booker) and Asda even for basic items. For instance
Lemon juice per litre
Tesco £2.20
Asda £1.56
Booker £3.29
Icing sugar per kg
Tesco £1.70
Asda £1.50
Booker £1.76
Fresh double cream per litre
Tesco £3.30
Asda £3.33
Booker £4.29
In all of the above cases the Booker packs were larger than the supermarkets. The Booker shop was a grubby warehouse with more leaks in the ceiling than members of staff. It can't be buying power as it's owned by Tesco. Free delivery only on orders over £100.
I can't work out why they're so much more expensive than normal supermarkets (and why caterers don't just get deliveries from the supermarket not Booker).
AIBU to be a bit confused?
