Satchmo has flexible pricing that allows you to price at multiple levels.
Pricing at the Item Level¶
You can create top-level Products, which are the things your customers see on the website. (Ex: Python Rocks shirt in demo store) Additionally, these products can have options (Ex: sizes, colors, etc). The product has a variation for each combination of options. This can be used to track inventory of particular product variations. (Ex: The Large, Blue, Python Rocks Shirt)
Effectively it works like: Product + Option = Variation
Pricing fits into the picture this way:
- You can set a default price on your Product.
- You can set a price adjustment for an option.
- You can set a price override for a variation.
The price code looks through these backwards. If the variation has a price then that is used Otherwise the Product price is used +/- the adjustment for the chosen options (IE: XL shirts are +$1.00)
With this capability, you can quickly price a simple store by just using the product prices, and possibly adding price adjustments for specific options, but you have the option of very fine-grained price control by setting prices for each variation.
Product Variation Prices¶
On the product variations, the price can have an expiration date and/or a quantity. If either of these fields are set then that price is only effective for orders placed before that date, or >= that quantity. The most specific of these gets highest priority (IE: the soonest expiration date, and the highest applicable quantity). This is useful for running temporary promotions that automatically expire.
If you are using expiring dates for prices, please note that you must run a daily update of the pricing lookup table. To do this, you need to run ./manage.py satchmo_rebuild_pricing
This command also helps every time when this error occurs: “Sorry, we don’t have any of that combination available.”
The easiest way to run this automatically is to use the excellent “Django_Extensions” app. We’ve already added a daily job to rebuild prices, so all you need to do is to ensure that the daily job is getting run via crontab:
# run every morning at 2:22 am 22 2 * * * /usr/bin/python /path/to/site/manage.py runjobs daily >/dev/null 2>&1
Alternatively you can directly execute the command via crontab:
# run every morning at 2:22 am 22 2 * * * /usr/bin/python /path/to/site/manage.py satchmo_rebuild_pricing >/dev/null 2>&1
Satchmo supports setting different price and discount tiers based on user groups. The most common reason a store owner may need this is if they want to offer different discounts or prices for a class of user. For instance, a user with a “Gold” membership may automatically get a percentage discount. Another common usage is for wholesale versus retail pricing.
This feature is optional and can be enabled by following these steps: Using it is quite simple:
- Add ‘satchmo_ext.tieredpricing’ to your INSTALLED_APPS.
- Run ‘manage.py syncdb’.
- In the admin site under ‘Auth > Groups’, create a user group for your desired tier.
- Add users to that group via ‘Auth > Users’ in the admin.
- Make a PricingTier, associating the group to the tier, and setting any default percentage discount.
- If you want specific tiered pricing for a product, then edit the product. You’ll see a new section, “Tiered Prices”, where you can set prices by tier.
The price resolution process is straightforward.
- If the user is anonymous or has no groups, use the non-tiered price.
- If the user has a group and that group has a tier:
2a. Look for explicit prices (see #6 above) for that product. If found, return it. 2b. Else return the non-tiered price reduced by the default tier discount percent.
- If the user has multiple tiers, return the lowest amount found in 2a & 2b.
Pricing tiers should not be applied to superuser or staff members and they are ignored for them. It is easy to create other unprivileged user account for testing or shopping.
