NextWarehouse offers the ADATA 64GB Premier UHS-I Class 10 V10 microSDXC Card with SD Adapter for $8.84 with free shipping. (Newegg charges pennies more.) That's pennies under our mention from three weeks ago and the lowest price we could find by $1, although most merchants charge $18 or more. It features read speeds up to 100MB/s.
With these companies, it might be easier than you think to negotiate your monthly bill down.
