When to GL vs RL on HubbuyCN Spreadsheet
GL (Green Light) means you approve the item for shipment. RL (Red Light) means you want to return or exchange the item. On the HubbuyCN Spreadsheet, the community generally recommends GL for minor cosmetic issues that are not noticeable when worn, while RL for significant shape errors, major logo misplacement, or wrong items entirely.
Pro Tip: Always compare your QC photos against verified retail photos from the same season/year. Seasonal variations in retail products can cause unnecessary RL requests. The HubbuyCN Spreadsheet community maintains updated reference albums for this purpose.
