Adorama offers the Canon Speedlite 430EX II Flash, model no. 2805B002, for $249 with free shipping. That's the lowest total price we could find by $30. (For further comparison, we saw it bundled with a diffuser and rechargeable battery 4-Pack with charger for $3 more on Black Friday.) This hot shoe flash for Canon EOS and PowerShot G series cameras features an AF assist beam, automatically zooms to match a compatible camera's image size, and more.
