This feature is a great way to suggest other products to your customers to increase your sales!
Navigate to System > Configuration > Catalog
In the Cross Sell Count field, enter the number of products you would like promoted on the Product Pages When a number greater than 0 is entered, Cross Sell Count, will display the number of products specified at the bottom of your product page. If you do not specify your own items in the cross-sell section on a product page then WSM software will select similar items in the same category for you.
To Specify Which Products Show On Product Pages
Navigate to the product where you would like to add Cross Sell items
Click the Items icon (looks like a box)
Click Add Product button
Type the part id or a portion of the name to see a list of products
Click the product from the generated list (See Tip)
Set Priority number 999 to 1 (the higher the number the closer to the top or right the product will appear. Any items with the same number will be sorted alphabetically)
Click the Add Cross-Sell Product Button
New functionality added 3/18
The WSM system is designed to pull items in to your cross-sell list from current sales and views
If you set the cross-sell item amount to 6 items the site would make up the 6 items from whatever you chose and what the system sees as current items.
What if you only wanted to show 4 items of your choice on a product, you can now do that when you select
TIP 1: Copy/Paste to Assign Cross Sell
Copying and pasting information from another source, paste the information into the product field.
Once you have pasted the information, use your backspace key to remove the last character from the pasted information (if this is a number keep it in mind)
This will generate the list of products available, scroll through the list and locate the item you want to cross-sell.
Continue with the instructions above
Troubleshooting - When using the cross sell functionality within the individual product there may be what appears to be multiple copies of the same item - do not use this feature, utilize the steps above
TIP 2: Products displayed without Restrict setting
The cross-sell returns the products that have most often been purchased with the cross-sell item and adds them to the cross-sell list up to the specified limit.
To put it another way; it queries all orders that have purchased the cross-sell product. It then does a count on each item and sorts so the highest counts are at the top. It then adds the items to the bottom of the cross-sell products list that is returned to the front-end.
If this option is enabled it would skip this query and only return products that are linked as a cross-sell item.
