Models can have small variations so you have to get the box and recheck out the specs and model numbers.
You omitted the BB link so I can't see if the BB model is a variant.
Hi, I am wondering if laptop specifications can vary within the same exact model number. specifically, the Acer Aspire E model # E5-575T-58WH on its own website lists 8g of DDR4 SDRAM, While on Best Buy's website the exact same model number laptop is listed with 8g SODIMM DDR3. The other discrepancy I found was Acer website says keyboard is backlit, while Best Buy says it is 'no'. Could there be a chance Best Buy website is wrong, or is this a common thing?
