I am thrifty & keep an eye out for good prices. I try to avoid buying from sources that may provide fakes. Recently bought two Sandisk USB memory products from Amazon.
An extreme 64GB USB 3.0 for US$32.24

A low profile SanDisk Ultra Fit CZ43 64GB USB 3.0 US$19.38

I also picked up a 512GB Samsung 850 Pro SSD for US$209.99. That is about $150 cheaper than the prices in Spore.
All these products were unlikely to be fake as it was being sold by Amazon & not just a sale by a 3rd party merchant where Amazon is providing fulfillment services. I'm a prime member & ordered other products totaling more than US$135, so shipment was free to Spore.
