Amazon offers Prime members the Sony 128GB UHS-I Class 10 SDXC Memory Card, model no. SFG1UY2/TQ, for $29.98 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $8.) That's tied with our mention from a month ago as the lowest total price we've seen. (It's also the best deal for this model now by $3, and it's among the least expensive 128GB SDXC cards we've seen.) It features transfer speeds of up to 70MB/s.
