Cloth in N Ireland usually has a nice selection of Oliver Spencer, and their sales are usually good. I've bought a few Universal Works items from them in the past. Customer service is great, but their site (which seems to be down at the moment) won't deduct VAT. But, they are quick to refund it if you send them an email. You'd have to be patient to receive your goods, as shipping can take upwards of a couple weeks to the US.
