With your Plus Membership you receive 10-50 credits a month (depending on your plan) to spend on products in the Plus Hub here - https://designbundles.net/plus. Each item in the Plus hub cost starts at one credit. Once you click on one to purchase it will go to your Plus Purchase page which can be found here for download - https://designbundles.net/plus-purchases.
If you don’t use all of your credits in the month they will roll over to the next month.
Another perk of your Plus membership is the after party deals for the $1 events. This means that you have 24 hours after the original event start time to purchase the items.
You will also receive 10-15% discounts (depending on your plan) on all regular priced purchases in the marketplace automatically.
