The phrase "don't bought" is not correct English grammar as it is the combination of two negative words, "don't" and "bought". A more appropriate phrase would be "didn't buy". However, if you are looking for synonyms for the phrase "didn't buy", some options include "didn't purchase", "didn't acquire", "didn't procure", or "chose not to buy". It is important to use proper grammar when speaking or writing in English, as using double negatives can be confusing for the listener or reader. Using clear and concise language will ensure effective communication.
