BB is the J435w and Amazon is the j425w..
Price for j435w on amazon is $99.. so better deal at BB.
J425w, J430w & J435w are the exact same printer according to Brother. I sent them an email asking if they could explain to me the difference between the 3 models & this was their reply:
"There are no product specification differences between these three models. The only difference is the design pattern on the top of the lid of the machine."
Best Buy has a long history of carrying products with slight physical design alterations (color, bezel shape etc) so they can give it a different model number and avoid price-matching.
