I dont usually recommend just one tackle shop, as every one has a different style and approach to dealing with their customers but one in particular has really made an impact on me, Padiham Angling Center in Padiham Lancashire, the owner Steve is a top notch bloke always willing to talk and get to know his customers, if he does not have something in stock he'll do his hardest to get it in for you asap, his bait is second to none, his maggots for example are really fat and healthy, I've not failed to catch with them.
They cater for every aspect of angling from fly fishing to sea fishing, I've always found exactly what i need when i go in and am always eager to look at his new stock (like a kid in a toy store)
If you live in east lancashire or come over for a fish in one of our numerous lakes rivers and canals then pop in and pick some gear up you wont be disappointed
Heres the webpage for the shop
