Qurbaani & Halaal Slaughter

Q: My husband is a student of deen and his parents help us for our living. I do teach and get a monthly salary alhmdulillah. From it I give 2/3 and keep 1/3 for me.

Now for qurbaani I wanted to do it here in South Africa but my husband said "the best in reward" is that I do in another country cheaper and give the extra with the 2/3. I do not mind giving.

My question is as follow: Will I get more thawaab in doing qurbaani here in South Africa or in doing somewhere else cheaper and giving the extra of my qurbaani budget to help with the expenses?
