Enough points for a CW seat to the USA or South Africa (at the old 800 conversion rate and with an AmEx voucher ).

The catch - you have to spend at least £2,564 in the New Catalogue!

Best deal (in points terms) seems to be £50 of CC vouchers for £350 spend on furniture (10,000 BA miles at 500 conversion rate) followed by £10 of CC vouchers for £75 spend on toys...
