What exactly do you mean by RP gifting? Does this mean that you are selling RP at a discount or some sort of code that can be redeemed in the official League of Legends client on your own account? Or are you selling accounts which already have RP in them? Also, how fast is your delivery? I am not into the account buying/selling market since I see no purpose in doing so (IMO one account in a game is more than enough). What are you selling that can be used in one's own account, exactly?
Riot point gifts are basically wards, icons, skins, champions, rune pages, mystery champions, mystery skins that are gifted from our accounts. We sell accounts and in some cases we get supplied accounts that contain RP so we opened a service gifting service
. Delivery for accounts stock is instant after your payment, paypal is instant and bitcoin transactions need confirmation. Gifting is a bit different, after completed payment we receive your order details and add you to in game friends as soon as our live support opens (8 a.m. to 10 p.m. GMT +2) and your gift will arrive after 24 hours from the purchase. It's not instant and people tend not to wait over saving money for rp however those are the riot rules in order to gift it takes 24 hours to be in friends list.
