Mummy’s market pre order

Hello! May I check if anyone did pre-orders from MM before (esp big items) and how do you go about arranging for delivery? Cos I bought quite a fair bit of stuff from the pre orders and after I paid, realized most are big and bulky (eg cot, stroller, bath tubs, etc). I did Fb message then asking about delivery and they said they will be providing the service but not sure when the details will be out. So wana check her if anyone ordered before in the past MM pre orders and how do we go about “collecting” it on fair day and arranging for delivery. Thanks!
