Is it better to buy a computer on my credit card, or on credit from the computer store?
Since you have a credit card, I recommend you use it for the purchase. It gets you two things at the very least: Gets the purchases reported as credit utilization. If you handle that correctly, you can improve your score Most card vendors give free extended warranty and return policies that a retailer or manufacturer does not without extra fees. I buy all my electronics using my cards and not only does that optimize my scores but I have been able to enjoy painless/better RMAs for defective products just because my AmEx card would have refunded me the money anyways and the retailers knew it (AmEx would have recovered it from them in the end so it was in their interest to resolve the matter within 30 days)
