HandyShopper is a great shopping list tool, with plenty of features.
You can even use it for other kinds of lists! HandyShopper works on Palm OS v2.0 through v4.0, on all Palm-based devices (including HandSpring, Sony, HandEra, etc).
Visit the HandyShopper User Group to get or share ideas, etc.
And best of all, HandyShopper is FREEWARE!
Update Description:
v3.1.2:
* Start a new lookup session when using the context menu, jog wheel, or D-pad to check off an item.
* Improved behavior on devices with D-pad Navigation (the blue aura around the active control); it should get in the way less now.
* Fixed Import when the thousands
separator is the space character.
* Fixed popup list of stores on OS 5.0 and higher to scroll the current store into view.
* Fixed Copy Item so that the item gets sorted into position after being edited.
* Fixed New and Copy Item so they can be undone.
* Fixed AutoOrder corruption; you may need to reset your AutoOrder information by going to the Preferences screen and choosing "Clear Order for Every Store" from the "Extras" menu.
* Other esoteric fixes.
v3.1.1:
- Fixed issues in HS3Convert when a database has AutoOrder information.
v3.0.6 - build 4406 - (August 6, 2008):
* Fixed a rare potential crash that could occur in a new empty database if stores were created before any categories or items were created.
* Fixed the center button in the Details screen to work properly on devices that support hardware navigation (the blue aura that highlights the current control).
v3.0.5 - build 4325 (July 25, 2008):
* On devices with a 5-way d-pad, the default action for pressing the center button now checks off the highlighted item. There is a new "Hold center button to check item" option in the Misc tab of the Preferences screen (not all devices support press+hold). The change in behavior is needed because the Treo detection fix in v3.0 build 3930 led to HS finally realizing that several other devices also had 5-way d-pads, which in turn led to some unexpected quirks on certain devices.
* The Details screen now supports hardware navigation mode on devices that have the hardware navigation feature (the blue aura that highlights the current control). Up/down still go to the previous/next item.
* The Best Buy screen now shows the percentage difference and unit price difference between the two products.
v3.0.4 - build 4313 - July 13, 2008:
* Using the d-pad Left button in the list of items now shows the Stores popup list, just like on the Windows Mobile version (previously it showed the Databases popup list).
v3.0.1 - build 4020 (April 20, 2008)
* Fixes: Sorting by category behaved unpredictably once a database was upgraded to the new category format (i.e. the new 100 category limit).
* The record counts in the list of databases were off by one for databases that were upgraded to the new category format.
* Under certain conditions soon after using Edit Categories the program could crash ("bad write to Categories list") or overwrite the wrong record.
* HS3Convert was only outputting the first digit for per-store prices.
