The amount of time it will take to receive your products from a supplier on Orderchamp will depend entirely on the lead time of the supplier. The 'lead time' is amount of time it will take from the moment the supplier approves your order until your order is delivered to you.
Lead times can be impacted by several different factors. It could be that the supplier you are ordering from makes everything handmade, following a very meticulous production process. Their lead time would therefore likely be longer than the lead time of a supplier who has product in stock ready to ship.
To view supplier lead times, visit their store on Orderchamp's platform and you will find the lead time just below the store name. Moreover, the lead time for your order specifically will be mentioned by the supplier in the e-mail you receive when he or she ships your goods.
