Paid for an item 2/12 on eBay, item shipped 2/14 after inquiring. GLS tracking showed 2/15 delivery, then rescheduled for 2/16. End of day I contacted them and they stated they didn't have the item but expecting to deliver by the 19th. After no updates, I contacted both GLS and eBay seller again and they updated their website for 2/20 delivery.
Please ask the seller who they use for delivery before purchasing if you want to avoid headache from frustrations.
