vildi ... verb, 3rd pers plural, past, subjunctive, active of VILJA
 
kaupa ... verb, infinitive
 
Sentence 1
vildu kaupa is in the indicative form because it is a definitive statement - wanted to buy
 
Sentence 2
 vildi kaupa is in the subjunctive form because it is in a dependent clause implying possibility - what they might want to buy
 
[The only example I can think of where we still have the subjunctive form in English is in
...If I were you, I would.....
but this would be less common in spoken English nowadays.]
