Bargain Topaz B&W Effects Software - Half-Price until 19 November.

[applemint]

Topaz B&W Effects Software is half-price until 19 November. ($29.99 which is just under 20 quid, with 'coupon code' novbw). Not quite as good as Silver Efex Pro imo (I have both) but still pretty decent and a bargain at half-price.
