Amazon offers the Transcend 16GB Class 10 Secure Digital High-Capacity SDHC Card, model no. TS16GSDHC10E, for $15.98 with free shipping ($1/GB). That's a buck under our December mention and the least expensive 16GB class 10 SDHC card we've ever seen without rebate hassles. (It's also a current price low for this class of card by $33.)
