Been using 6PM off and on for years with no problems. But the last order I placed, for almost $150, never arrived. Of course I checked with my neighbors, etc. Called Customer Service and told them - that package never arrived, even though the status said Delivered.
They quickly admitted that they have a new delivery service and have had problems. They refunded me immediately.
I am rating them 3 stars because I am concerned about this happening again. But the discounts are worth another try!
