+I would like to sell my gift card steadily.

[galacticarm]

Bot club is for selling items tradable between Steam users, like CSGO gun skins. The benefit for that subscription does not apply to selling for example gift cards.

Compare the three other subscriptions at Gameflip | Buy & Sell Games, Gift Cards & More - Gameflip
The Cost is what you pay for the subscription every 30 days. The Commission and Digital Fee are the percentages that apply to your sales.

Sell Comision in pro club

Commission and fee are what Gameflip takes from your sell price. Suppose you sell a gift card code for $100, there’s a 8% commission and 2% digital fee so you get $90 total (100 - 100*(0.08+0.02)). All subscriptions have a 0% digital fee. Gamer Club subscription has 0% commission but you can sell up to $50 worth of items. Pro Club has a 6% commission but you can sell up to $500 worth of items. https://gameflip.zendesk.com/hc/en-us/sections/115000044274
