I ordered two Nikon lenses from Jumbo Packages at low cost. Received Email asking me to call. Then was told that the credit card that the web site had accepted was not being accepted anymore so I had to use a different credit card. Then was told that there would be a insurance/handling charge that the web site and the invoice I received via Email did not disclose. Also pushed to sell me other items, some of which were listed as being included with the lenses.
Even after talking them out of the insurance charge and agreeing to buying a couple of warranties they still failed to ship the products which the web site indicated they had in stock. Finally got tired of waiting and Emailed them with a cancellation notice, twice, and asked for confirmation which I never received. Received two more Emails requesting that I call to confirm my order, called and cancelled the order again. The person on the phone said that calling was the only way to cancell an order, but they could have Emailed me back and told me that. Along with the hasselling and the delay in filling the order I cancelled it by phone.
My advice, don't let the low prices lull you into dealing with these people.
