In a browser log into Social Club[socialclub.rockstargames.com]. Then in left top corner of the page choose Games > Red Dead Online > Catalogue.



Now in right top corner of the page choose Online.



Choose an item you are interested in. For example, I will show you arrows for the bow. Go to Sporting Goods & Guns and on the left choose ammunition for a specific weapon class. We're looking for an arrows, then click quick buy.



Choose an amount of ammunition from the drop-down list (up to 1000 and a 100 for other items) and confirm the purchase.



That's all! Your items will be in the locker in the camp or at the post office. I hope I made your life easier =).
