Capilano Honey's suitors have sweetened their offer despite the company's sales taking a hit from an attack casting doubt on the integrity of some of its products.

Albert Tse's Wattle Hill and Roc Partners Investment Fund increased their offer from $20.06 a share to $21 a share on Friday as billionaire Kerry Stokes, who holds 23.12 per cent of the stock, reaffirmed his support for the $198 million takeover bid.
