Those are good options. p2p no-fee would definitely be helpful, that is why I was considering it before. But the one providing the Fiat is taking most of the risk, since they're taking a stablecoin that has little upside, and will incur the fees if they want to convert it to Fiat themself. I can technically put the HBD to the savings, I just don't have enough funds or liquidity to steadily provide the Fiat haha. There is also the option of the store making a Hive account, and making me a small beneficiary in their rewards.
As for other discounts, I was actually thinking that the store can encourage the clients to make a Hive account, and post about their order and experience. The store and I can upvote it [with what little upvote power we have] to get them started, and maybe ask HivePH for some support as well. The store can give a discount on their order for their efforts [or I can pay for the discount].
There are a lot of options, but no funds haha.
