They gave me the runaround on a Nikon Fisheye 8-15mm that was 'unbelievably' priced about $200 less than standard MSRP... after I placed the order, they called to confirm that I understood it would not ship with the lens cap or end cap, nor would it come with the soft case it is packaged with (even though their site shows a "compare to" price that is compared to the standard lens packaging). They said it was a 'wholesale' version instead of 'retail' version.
I found the lens cap, end cap, and bag for a total of about $40 so I said fine, send me just the lens.
Then they called me two days later to tell me that actually the lens was out of stock, but if I wanted the 'retail version' at full price, they could ship it right away - a clear bait and switch.
I researched AbesofMaine and found tons of complaints against them.
I added my own complaint on Consumer Reports, and they then replied on Consumer Reports that they would honor the original deal - of course, by that time I'd already ordered and received the lens from UniquePhoto.com.

Suffice to say, I will never do business with Abe ever again.
