Self descriptive really. Found in Chester Sealand Rd. store, but confirmed that the deal is nationwide
Great deal to me. The next cheapest I could find was £51 off play. It's £50 off PriceMinister if it's a first purchase. Other than that, prices for it are ridiculous. £65 on Amazon Marketplace and £81 at Base but >£100 everywhere else. A solid £140 from Amazon! They're even selling used on eBay for £40ish, so probably not a realistic money making opportunity, but definitely a steal.
I'm guessing Tesco is having some sort of a DVD Boxset sale as this is not the only cheap boxset. Sopranos and The Wire have already been posted
