You just gotta:
- make an account
- Find a store with items that you want, for example, say you want a Ultimate Dume mask, you would search it up in "parts", then click View on the one you want, then find other stuff in the store that you want to buy.
- Once your cart has everything that you want in it, go to the checkout and select your payment method (I use Paypal)
- You will then receive a confirmation of your order.
- Within a few days you will receive an invoice, telling you how much the order will cost with the postage, which you must pay to the seller.
Tips for stores:
- Use stores with good feedback
- If you want to only buy single items, like 1 mask, try to choose a store in your country, otherwise you will end up paying more for postage than for the item itself.
- Buying the cheapest one isn't always good. Say you want a Gold Avohkii and a White Hau, and in one store the Avohkii is $15 and the Hau is $7, but in another store they are both $9... The store where they are both $9 is better, even though you are paying more for the Hau.
Hope that helps.
