I've bought several times from Abe's of Maine, and each time I've received an upsell call afterwards. Each time I politely told them I wasn't interested in what they were pushing, I verified my information, and I got the gear a few days later. No big deal, it's how they justify their lower prices.
How recent was this? Is this before, or after their bankruptcy (November 2012)?
Prior to their bankruptcy, when they were an authorized dealer, the above was definitely true, and if you firmly said no they'd leave you alone and ship your order.
These days I have not heard of a single person yet who has had their order shipped successfully -- but there's always a first.
