i visited northampton in march. there are factory outlets from church`s, lobb, trickers and c&j. eg has their factory there as well, but not a real factory shop afaik. unfortunatley i could only visit trickers and church`s, because we ran out of time. c&j btw is only open friday. at trickers i bought two pairs for 180 gbp each. these were both standard items from their catalog. the seconds at trickers sell for about 80 gbp a pair. at church`s i bought a pair of seconds for 140 gbp. both factory shops had a large selection of seconds. and at lest at trickers you can buy anything they produce at reduced prices. if anyone goes there ask for david and greet him from me
for the adresses and more info take a look at the german shoe-site www.dailyshoes.de
if you enter trickers and northampton in the search ("suche" in german) you can find the threat.
