英国采购需求：快递包裹袋，物流配送袋，分拣配送袋，编织分拣袋

I'm interested in purchasing large courier bags similar to those used by Amazon and would like to know what color options are available. It's important for us to have variety, so if you could provide details on the colors you offer, that would be great. Additionally, please let me know the minimum order quantity required for these bags along with the pricing information. It would be helpful to understand any bulk order discounts you may offer as well. Looking forward to your prompt response!
