Newegg offers two Patriot 32GB Signature Series UHS-I Class 10 microSDHC Cards with SD Card Adapters, model no. PSF32GMCSHC10BK, for $27.99. An $8 mail-in rebate cuts the price to $19.99. With free shipping, that's only $6 more than today's earlier mention of one card and the lowest per-card price we've seen. (It's a current low of $12 for this quantity elsewhere.) Each card features write speeds of up to 20MB/s and read speeds of up to 40MB/s. Rebate expires August 25.

Update: Shipping has increased to $1.92.
