We use a single account for all shopping sites as we want to centralise our carts, but this works poorly on gifting/surprises.
We're on Singapore so what we mainly use are:
  • Lazada (sad that LiveUp is cancelled)
  • Shopee (Shopee Mart is oftentimes faster)
  • Amazon (Prime is only S$ 3 monthly, no-brainer for Prime Now and free delivery option)
  • Zalora (also signed up for Zalora Now as we're suckers for ultra fast shipping)
  • foodpanda (duh!)
As for paying, we mainly use my credit card which is connected to our phones' Apple Pay in case we need to buy something from a store.
