The Summer Sale offers a 20% discount on individual products or suites but does not allow for use with any other offer (an upgrade). Upgrades provide up to 50% off products to help customers move up to a new version.
From an individual product standpoint, the sale is very straight forward, you either get 20% off the product or you can take advantage of the better "upgrade" discount if one is available to you. The WebAssist upgrade policy takes 50% of the highest priced product purchased and applies that to the cost of the suite if you are moving up from one or more products to a suite.
Where it gets difficult is dealing with the suites because of the numerous ways customers could have purchased individual product combos that make up the suite and the prices that they paid for one or more of the products that they purchased. Because of this, there are situations where the 20% summer sale might be a better deal than taking advantage of an "upgrade offer". This really plays out with those who purchased individual products rather than going with a suite out of the gate.
If you have any questions regarding your specific upgrade needs, please call into our sales team to discuss potential options for you.
