The iPad Pro now costs $50 more even though the features are the same

• Apple increased the price of two iPad Pro 10.5 and iPad Pro 12.9 models by $50.
• Both tablets still have the same features.
• Apple says the price increase reflects shortages by suppliers of flash memory modules.

Apple quietly increased the price of the 256GB and 512GB versions of its 10.5-inch and 12.9-inch iPad Pro tablets.

The price change was first spotted by the blog MacRumors.

Prior to Tuesday's Apple rollout, consumers could purchase the 256GB and 512GB 10.9-inch iPad Pro for $749 and $949, respectively. Those models now cost $799 and $999, respectively. The 12.9-inch iPad Pro saw its 256GB and 512GB models increase by $50 to $949 and $1,149, respectively, with the latter nearing the price of a MacBook.

The price of the 64GB version of both iPads remains unchanged.

Apple told CNBC the increase is due to suppliers' price increases for NAND memory chips, which provide storage in iPads.
