Mega Sales Lite extension allows you to set special prices for entire product categories, manufacturers, products with specific filters, and for their combinations (category and manufacturer and filter combinations).

You can put all products from the store for massive sale in one click.
You can put all products from any product category for massive sale in one click.
You can put all products from selected manufacturer for massive sale in one click.
You can put all products with any product filter for massive sale in one click.
You can put all products with specific filter, manufacturer and category combination for massive sale in one click: for example Red (filter) CaseLogic (manufacturer) computer cases (category).
You can select when sale starts and ends (date), what discount is applied. Discount can be set by percentage, or by specific value off the price.
When you start a new massive sale, all the other product special prices are removed automatically.
You can have one massive sale at the time, but setting special price for any other product that is not in specific category can also be set.
To be able to set massive sale by product filter your store must have filters (Admin >> Catalog >> Filters) and product filters selected.
Do not use it for products that have options with different prices – OpenCart cannot set Specials for Options, so this extension also won’t set them.
