っとけば

[Lomaster]

Occasionally i come across っとけば constructions, as in 「コニーの言うとおりウエポ買っとけばよかった」
While i suppose it serves the same purpose conditional ~ば constrictions do, i'd like to know the nuances.

～とく is the contraction of ～ておく.

Just when i was about to ask if there's a list of such contractions like ちゃう、とく etc. i've noticed the wiki link. Thanks, Toritoribe!
