The original purchases were from Amazon, the first monitor being from a highly rated merchant for the open box deal, and the U2715H was directly from Amazon, new. The replacements were dispatched from Dell Support directly under their warranty service, not from Amazon. What they sent as replacements were refurbished and in horrible condition, however it appears Dell uses third parties for repairing and shipping of replacements due to the packing slip / comment sheet having a separate supplier on them.
