Delivery range I believe. I try to avoid Amazon as much as possible.Delivery Range or the products? I found the selection there very lackluster especialy compaired to amazon.
Amazon sometimes has crazy prices which is why I need a backup. For example, the filters for Kabuto's pioneer pet raindrop fountain are twice as much on amazon as they were at pet valu. $7 per filter on amazon vs $4 per filter at pet valu.
I knowEveryone is skyrocketing their prices... stupid inflation.
