The more payment methods, the better. Although, I don't think that anyone is going to buy with bitcoin currently. You realize that he/she has to pay product's price + ~$7 in order to get the transaction quickly confirmed. If the fee was much lower I would suggest adding it.
Sure, the transaction fees are quite high right now... but my products are selling for about 100-150$ so it may even work.
Regardless of the price, if your product is worth buying. People buy.
This trade should be thought of in terms of value fungibility: if the product isn't delivering equal or greater returns per annum over a 5-10 yr time horizon, it is not worth buying with Bitcoin.
