Fry’s via Google Express has the Raspberry Pi 3 Model B+ for $28 ($35 – 20% code GADGET20) plus tax. I bought four to maximize savings from the 20% off ($150 is the sweet spot because the maximum discount is $30).

This should be less expensive for most people than the Micro Center deal ($29.99 limited to one and in-store pickup only).
Google Express 20% off (up to $30) select computers, tablets, headphones, and calculators with code GADGET20. Expires 7/27/2018. Limited to the first 5000 customers. Walmart and Costco products are excluded.
