Discounted iStock Credit Packs with Our Exclusive Promo Code

iStock offers various promo codes for credit packs, including those offered exclusively by Photocase. Using a code for a credit discount is the smartest way to buy stock photos (and videos) on demand. 

While subscriptions are great for creatives who need a high volume of images regularly, and they have the lowest price points across the board, credit packs are the gold standard for users who want image downloads that aren’t tied to expiration dates and recurrent payment commitments. 

Combining promo codes with strategically chosen credit packs, you can get the flexibility you need at the lowest possible price.

Larger Packs = Bigger Discounts

iStock’s credit packs have a clear bulk-discount structure: the larger the pack, the lower the per-credit cost (and therefore, the less each download will cost). 

On top of that, our credit discounts are also tiered according to volume: 

  • The 15% off code applies to all credit packs
  • Our exclusive 25% off code is specific to packs of 18 credits or more

The iStock system is designed to reward bulk buyers who are willing to pay for more credits upfront. Still, it’s worth noting that the reward isn’t just monetary but also functional: iStock’s credits are valid forever, as long as you log in to your account at least once a year, all credits in it remain active. 

Knowing this key information is what helps you make informed, clever purchases. Say you were planning to buy 12 credits; you can still do it and save 15% using the site-wide promo code, or you can opt for the 18-credit pack and save 25% with the large credit pack code, obtaining more downloads for a much lower per-credit price, without worrying about when to use them up because they’ll never expire.

What Can You Buy With Credits?

Basically, anything. One of the best things about iStock’s credits is that they’re good for downloading images and videos from both the Essentials and the Signature collections, indiscriminately. The only thing that changes is the number of credits needed for each asset, but the same credit pack lets you download any asset you wish. 

Add to this the fact that they never expire, and you have one of the most flexible and risk-free on-demand offers ever. Imagine you can buy 60 credits today and use them to download images and videos, both everyday-style and high-end, at your own pace, for the next few years.

Existing Customers: Do Codes Work on Credit Top-Ups?

Yes, they absolutely do. iStock’s promo codes, including Photocase’s exclusive 25% discount on large credit packs, apply to existing accounts. 

This means if you’ve run out of credits, you can simply apply the code at checkout for your next refill. 

But you don’t have to wait, either; you can buy a new credit pack with the discount even if you still have credits. Older and newer packs can coexist, and all remain valid in your account for your use at your discretion.

Is Your Credit Code Not Working? Troubleshoot 

If you tried to use a promo code for credits and it didn’t apply, there are several steps you can take to resolve it quickly. Check this brief troubleshooting list: 

  • Is the pack size too small for the code? Remember the 25% code has an 18-credit minimum; if the pack is smaller than that, it will not work. 
  • Is there another code already in the cart? iStock’s checkout system allows only one code at a time, and sometimes a code, such as their “welcome” 10% discount for new customers, is automatically applied. Check, and if there is, simply delete that code and replace it with our promo code. 
  • Are you in the right checkout page? On the iStock checkout page, you should see a summary order on the right side of the screen with a green “Have a promo code?” link that reveals a text field when clicked. 

Buy iStock Credits at Super Low Cost with a Promo Code

Now you’re aware of how the credit system works and the ways to maximize your investment using a promo code, the only thing left to do is decide how big a pack you’ll get, grab the promo code from this page, and head over to iStock to start downloading!
