Product Tier Pricing as Percentage Extension
The tier pricing system in Magento is a nice feature, but it certainly needs some attention. We’d like to see the tier prices manageable via dataflow for a start, and a nice feature would be to create tier pricing rules and apply them en masse. I have developed a quick extension which allows merchants to enter a percentage to mark the discount of each tier. This then calculates and automatically fills in the actual price for each tier.

This version only works on Magento 1.4, 1.5 and now I know it works on 1.6 too.

How it works…
Couldn’t be much simpler really. Once you’ve uploaded the files via FTP, when you edit or create a new product you’ll see an extra input field added to the table. The form doesn’t save what’s entered here. You enter it once and it calculates the price. You must have first entered the original price of the product – it does not count a special price.

For example if your base price for the product is £14.20 and you want there to be a 10% discount if the customer buys 2, you’d enter 90. If the discount was 20% you’d enter 80 and so on.
Thanks for reading the Magento Blog at Ecommerce Web Design. Let me know if you face any problems with this extension and I’ll get it updated asap..

Hello, I’m testing this module on Magento 1.6.2, and it looks like it works. Thank you!
Awesome, thanks for the update Jarek.
I FTP’d this over but am not seeing it enabled, do you have an installation faq?
