Raisin' Some Raisins

I wanted to remember to buy raisins the next time I went shopping, so I opened my shopping list app on my cell phone and started typing the word “raisins”. Before I could finish, the auto complete in the shopping list app suggested I use the word “raisin” singular. This suggests to me that according to the shopping list app's algorithm, more people buy a single raisin individually than in bulk.
