Credits can be used to order responses from the UsabilityHub panel.
Credits can be purchased on-the-go when ordering responses, or you can pre-purchase credits in bulk. When you pre-purchase, you and your team can spend the balance of credits to order responses on tests at any time. Credits do not expire.
Bulk credit discounts
Credits cost $1.00 USD each and are available at discounted rates when you pre-purchase 1000 or more.
These discounts apply whether you purchase credits while placing a response order or pre-purchase them to hold in your account balance. However, discounts only accrue within a single purchase, so if you intend to place a number of orders you may get a lower price by pre-purchasing your credits.
You can pre-purchase credits from this page: https://app.usabilityhub.com/credits/purchase.
